        v = new int [3][3];
        for(r=0;r<=2;r++){
            for(c=0;c<=2;c++){
 
                v [r][c] =  new Double(Math.random() *10).intValue();
 
                System.out.println("["+v[r]+"]" + "["+v[c]+"]");
            }
            may = v[0][0];
            for(r=0;r<=2;r++){
                for(c=0;c<=2;c++){
                    if(v[r][c]>may){

You're are seeing the toString() result from an array of int. If you want to see what v[r] holds consider using Arrays.toString(v[r]):

Code java:

---

// at the top:
import java.util.Arrays;
 
    // in your for loop:
    System.out.println("[" + Arrays.toString(v[r]) + "]" + "[" + Arrays.toString(v[c]) + "]");
