------But im getting this-------

I have a txt document as well, so the code works, it just prints out this mess...

How can i fix it?

Here's my code:

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Arrays;
import java.util.Scanner;

public class myArrayLab {

public static void printArray(int arr[]){
for(int i=0;i<arr.length;++i)
System.out.print(arr[i] + " ");
}
public static void printArray2(int arr[][]){
for(int i=0;i<arr.length;++i){
for(int j=0;j<arr.length;++j)
System.out.print(arr[i][j] + " ");
}
  
}
public static void printArray3(int arr[][]){
for(int i=0;i<arr.length;++i){
for(int j=0;j<arr.length;++j){
if(i==j)
System.out.print(arr[i][j] + " ");
}
}
  
}
  
public static void Sort1(int arr[]){
Arrays.sort(arr);
}
  
public static void main(String[] args) throws FileNotFoundException {

Scanner sc = new Scanner(new File("input.txt"));
int arr[] = new int[10];
int i= 0;
while(sc.hasNextLine()){
arr[i++] = Integer.parseInt(sc.nextLine());
}
  
System.out.print("Ages:");
printArray(arr);
System.out.println("Ages:");
Sort1(arr);
printArray(arr);
System.out.println();
int array2d[][] = new int[5][5];
printArray2(array2d);
System.out.println();
printArray3(array2d);
}

}

Explanation / Answer

HI, Please find my implementation.

Please let me know in case of any issue.

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Arrays;

import java.util.Scanner;

public class myArrayLab {

   public static void printArray(int arr[]){

       for(int i=0;i<arr.length;++i)

           System.out.print(arr[i] + " ");

       System.out.println();

   }

   public static void printArray2(int arr[][]){

       for(int i=0;i<arr.length;++i){

           for(int j=0;j<arr.length;++j)

               System.out.print(arr[i][j] + " ");

           System.out.println();

       }

       System.out.println();

   }

   public static void printArray3(int arr[][]){

       for(int i=0;i<arr.length;++i){

           System.out.print(arr[i][i] + " ");

       }

       System.out.println();

       for(int i=0, j=arr.length-1;i<arr.length && j>=0;++i, j--){

           System.out.print(arr[i][j] + " ");

       }

       System.out.println();

   }

   public static void Sort1(int arr[]){

       Arrays.sort(arr);

   }

   public static void main(String[] args) throws FileNotFoundException {

       Scanner sc = new Scanner(new File("input.txt"));

       int arr[] = new int[10];

       int i= 0;

       while(sc.hasNextLine() && i < 10){

           arr[i++] = Integer.parseInt(sc.nextLine().trim());

       }

       System.out.print("Ages:");

       printArray(arr);

       System.out.print("Ages:");

       Sort1(arr);

       printArray(arr);

       System.out.println();

       int array2d[][] = new int[5][5];

       int num = 1;

       for(int k=0; k<5; k++)

           for(int j=0; j<5; j++){

               array2d[k][j] = num;

               num++;

           }

       printArray2(array2d);

       System.out.println();

       printArray3(array2d);

   }

}
