What can a court do before and during to allow a fair trial regarding media attention?

I am trying to write name, age, salary and record to text file.

All variable are given value by input. My out.write line is not working.

class Text extends Writer

{ PrintWriter out = null;

public Text(String fileName) throws IOException

{

out = new PrintWriter (new FileOutputStream(fileName, true));

}

public void write(String name, int age, double salary, int record)

throws IOException

{

out.write(name, age, salary);

}

public void close()

{

out.close();

}

Still having problems... I cannot figure out how to make my Complex parseComplex(Strign str) method work. I have to use string tokenizer. Can someone point me in the right direction on my code and what I need to return from that method? Thank You:)

package lab1;

I am trying to use String Tokenizer and add two complex numbers here are the methods I am having problems with. The user enters the complex numbers as a string, and then it is split into tokens.

public Complex add( Complex c)

{

return new Complex

(real+c.real, imaginary+c.imaginary);

}

public static Complex parseComplex(String str)

{

Complex token = null;

StringTokenizer st = new StringTokenizer(str);

while (st.hasMoreTokens())

{

System.out.println(st.nextToken());

// throw new NumberFormatException();

// throw new NoSuchElementException();

}

return token;

Looking for someone to write out a tab or sheet music for the lyric part of this song here http://www.youtube.com/watch?v=2yaRjWfwWPI

Goals: Implement searching algorithms and time them to see which approach is best.

Description

1. Create a new project called Lab8; the class files will comprise a package named Search. This project will be a Java Application, not a Java Applet. Make sure that you select the create Main Project check box after selecting file/new/Java Application. You won’t have to change the Project Properties.

2. This lab creates a GUI application that evaluates three search methods (linear, binary, and the built in Java collections search). A screen shot of my implementation follows.

3. My Implementation has three classes. These are Main, MainPanel, and Searcher.

4. This program randomly generates a set of strings where each string is a particular size. It then performs a series of search operations on the data and times how long it takes. The results show in the labels at the south side of the GUI panel.

5. The GUI structure is very similar to lab 7. You might review those instructions for hints. The main differences follow:

a. In this lab there is a drop down selection where the user selects number of searches to be done. There was no corresponding entry in lab 7.

b. The search type dropdown menu selections are linear, binary, and generic.

c. The Searcher class implements methods for each of the three search categories. These methods are presented in the week 7 slides.

d. The Searcher class has a String[] doSearch(int len, int n, int , int tries, int type) method, instead of String[] doSort(int len, int n, int type). In a loop, this method randomly picks a string from the data generated and then calls the appropriate search method.

class A

{ int i=1;

static int j = 3;

void m() { i = 5; }

static void m1() { j = 7; }

}

class B extends A

{ int i=2;

static int j = 4;

void m() { i=6; }

static void m1() { j = 8; }

}

In the main method we have statements

B b = new B();

A a = new B();

Answer the questions below, indicating the class method and variables affected.

a. Which method does a.m() call?

b. Which method does a.m1() call?

c. Which method does b.m() call?

d. Which method does b.m1() call?

e. Which variable does a.m() update?

f. Which variable does a.m1() update?

g. Which variable does b.m() update?

h. Which variable does b.m1() update?

I need to sum all odd numbers between 1 and 100 using a for loop, while loop, and do while loop. Help?

Write a method that prints the days in a particular month. It should have the following signature shown below. You can assume that any year evenly divisible by 4 is a leap year.

int daysInMonth(int month, int year)

I need help splitting my program in to separate methods all in one class. the program inputs the size of an array, find max min and average.

import java.util.Scanner;

import java.util.Arrays;

public class GradeArray

{

public static void main( String argv[] )

{

Scanner keyboard = new Scanner(System.in);

System.out.print( "How large do you want the array? " );

double[] theArray = new double[keyboard.nextInt()];

for( int i=0 ; i<theArray.length ; i++ )

{

System.out.print( "Enter value " + (i+1) + ": " );

theArray[i] = keyboard.nextDouble();

}

Arrays.sort(theArray);

System.out.println("The lowest is: " +theArray[0]);

Arrays.sort(theArray);

System.out.println("The highest is: " + theArray[theArray.length-1]);

double sum = 0;

double average = 0;

for (int i = 0; i < theArray.length; i++) {

sum += theArray[i];

}

average = sum / theArray.length;

System.out.println("The average is: " + average);

}}

I need to write a java program that asks the user how many number will be in the list. The input is stored to an array list. The highest number, lowest number, average number is then found. There needs to be a method to get input, find high, find low, find average

Program inputs the type of package, shipping option, and weight. The problem is in the else if (tos == 2){ section. When tos = 2 or three it uses zero for cost, if I do not declare that cost = 0 in my variables I get a variable may not have been initialized error. Any Ideas?

Here is my prompt:

Design and implement a class to represent a single multiple-choice question on an exam. Each question consists of a section that asks the question, and then four choices of answer, each of which is a letter followed by the answer. For example:

What type of method is typically declared as private and static?

Constructor

Instance

Class

Helper

The class should have attributes for the question, the four answers, and the correct response. An example call to a constructor for this class would be

ExamQuestion q17 = new ExamQuestion(“What type of method is typically declared as private and static?”, “Constructor”, “Instance”, “Class”, “Helper”, ‘d’);

The class should supply accessor methods that return each of the attributes as well as supply a method that prints the question on System.out in the format shown above.

Develop a separate driver class that could be used to test this class. This class should:

Create 2 instances of the Exam Question class, with two different questions (your choice of topic).

Display the first question, the four possible answers (using the ExamQuestion’s print method)

Get the user’s answer and display the correct answer.

Display the second question and its possible answers (using the ExamQuestion’s print method)

Get the user’s answer to the second question and display the correct answer.
