John

and how did Thomas Jefferson change the criteria?

Say that a text file looks like this:

x= 10

y= -45

y= 98

x= 13

x= 37

y= 36

x= -2

. . .

Each line starts with "x=" or "y=" but which of these it starts with follows no pattern. Each of these is followed by a space then a single integer. Nothing else follows the integer on a line.

Write a program that reads in this data file and computes the sum of the x values and the sum of the y values. Hint: use hasNext() and next() to read the "x=" and "y=" tokens and then use nextInt() to read the integer. You will also need the equals() method of String.

I need major help can someone help me any way possible

Write a program that reads a text file that contains groups of integers that start with the word "next". For each group, the program computes and writes out the sum of integers in that group. There may be any number of groups. Example data set:

next

12 45

92 -12 31

next

42 51 275 82 -274

-1 0 26 365

-56

72

next

90 93 91 95

97 96 98

For this data the program writes:

Sum of group 1 is 168

Sum of group 2 is 582

Sum of group 3 is 660

Here is another set of data:

next

1 1 1 1 1 1

next

next

1 1 1 1 1 1 1 1 1

next

10 11

12 13

7 8

9

For this data the program writes:

Sum of group 1 is 6

Group 2 contains no data

Sum of group 3 is 9

Sum of group 4 is 70

The logic of this program is quite tricky.

CAN SOMEONE PLEASE WRITE OUT THIS PROGRAM
