sometimes clients and servers exchange roles with clients becoming servers at times, whats an example where a client always remains the client never becomes the server.

**** IN THE FIRST LINE, WHAT I NEED IS FOR WHEN THE USER ENTERS A NUMBER THAT IS NOT IN THE 10 - 20 RANGE FOR IT SHOW THE ERROR BUT!!! START OVER FOR THE TOP SO THE USER CAN RE-ENTER ANOTHER NUMBER. THE ISSUE THAT IM HAVING IS THAT THE PROGRAM CONTINUES ON WITH/AFTER THE FIRST ERROR. I SIMPLY JUST WANT IT TO START OVER******

import java.util.Scanner;

public class Project_3 {

public static void main(String[] args) {

//Varibles

int range, direction, i, attempts = 0;

boolean repeat = true, test;

//Code

Scanner scan = new Scanner(System.in);

//To run again if wanted

while (repeat == true) {

System.out.println("----------Counter------------");

System.out.println();

do {

//Capture input from user

System.out.println(" Enter the value for how many times to run the loop. Must be between 10 and 20:");

range = scan.nextInt();

if ((range >= 10 && range <= 20)) {

test = true;

} else if (range < 10 || range > 20) {

test = false;

System.out.println("Error, invaild entry!");

System.out.println();

}

System.out.print("In which direction do you wish to count?"

+ " Enter 1 to count up and -1 to count down: ");

direction = scan.nextInt();

//Test if user input is valid

if (direction == -1 || direction == 1) {

test = true;

} else {

test = false;

System.out.println("Error: Invalid Entry: ");

attempts = attempts + 1;

}

} while (test == false && attempts < 3); // if false try again

while (test == true) {

//For loop

if (direction == 1) {

range = 0 + range;

for (i = 0; i <= range; i++) {

System.out.println("The value of i is: " + i);

}

} else {

range = 0 - range;

for (i = 0; i >= range; i--) {

System.out.println("The value of i is: " + i);

}

}

test = false;

}

System.out.print("Repeat? (true/false)");

repeat = scan.nextBoolean();

attempts = 0;

}

}

Pre Cal homework

Java issue, my answer is not coming out correct. The question is, Write a program that prompts the user to enter an interger from 1 to 15 and displays a pyramid.

The pyramid should look like

_____1

____212

___32123

__4321234

_543212345

65432123456 (EXCLUDE THE UNDERSCORES) and so on, BUT I keep getting >>

1

212

32123

4321234

543212345

65432123456

I AM USING NETBEANS AND THIS IS WHAT I GOT. WHAT CAN BE CHANGED OR ADDED??

import java.util.Scanner;

public class Exercise04_17 {

/**

* @param args the command line arguments

*/

public static void main(String[] args) {

// TODO code application logic here

Scanner input = new Scanner(System.in);

System.out.print("enter lines: ");

int k = input.nextInt();

for (int i=1; i<=k; i++){

for (int j=1; j<=i; j++){

System.out.print(" " +j);}

System.out.print("\n");

}

}

}

Wind chill formula is -->> Wind chill temperature = 35.74 + 0.6215T - 35.75V^(0.16) + 0.4275TV^(0.16)

The program should prompt the user to enter a temperature between -58 degrees F and 41 degrees F, and the wind speed greater than or equal to 2 which will display the wind chill temp.
