INSTRUCTIONS:-
- Modify example four to read integer values from the keyboard, store them into a 15 element array, then write the array into a file named userin.txt
- Write a program to create two files with the names file4.txt and file4a.txt
- two 10 element int arrays with the names arrfile4 and arrfile4a; these arrays are to have different values
-
write the contents of arrfile4 to file4.txt
write the contents of arrfile4a to file4a.txt
exampleFour
In the while loop, this program reads fileLoop.txt until all items are read;
Each item in the file is stored into an array
package storeintoarr;
import java.util.Scanner;
import java.io.*;
public class Storeintoarr {
public static void main(String[] args) throws IOException
{
File loopfile = new File("fileLoop.txt");
Scanner getAll = new Scanner( loopfile );
// connect a Scanner to the file
int num = 0, square = 0;
int[] items = new int[10];
int i = 0;
while(getAll.hasNextInt()){
num = getAll.nextInt();
square = num * num ;
//System.out.println("The square of " + num + " is " + square);
items[i] = num;
System.out.println("items[i] is " + items[i]);
i = i + 1;
}
getAll.close();
}
}
