Exploring Matricies in Java

Problem:

Write a program that prompts the user to enter the length of a square matrix, randomly fills in 0s and 1s into the matrix, prints the matrix, and finds the rows, columns, and diagonals with all 0s or 1s.

Output:

Enter the size for the matrix: 4
1000
0111
0101
0100
No same numbers on a column
No same numbers on a row
No same numbers on the major diagonal
No same numbers on the sub-diagonal

Solution:

import java.util.Scanner;
public class ExploringMatrix
{
  public static void main (String[] args)
  {
    Scanner scan = new Scanner(System.in);
    System.out.print("Enter the size for the matrix: ");
    int size = scan.nextInt();
    int[][] m = new int[size][size];
    
    for (int i =0;i<size;i++)
    {
      for (int j =0;j<size;j++)
      {
        m[i][j] = (int) (Math.random()*2);
        System.out.print(m[i][j]);
      }
      System.out.println();
    }
    boolean letitbe;
    //Row
    int j =0;
    
    boolean row=false, column=false, major =false, sub = false;
    for(int i=0; i<size;i++)
    {
      letitbe = true;
      for (j =0;j<size-1;j++)
      {
        if (m[i][j] != m[i][j+1]) letitbe = false;
      }
      if (letitbe)
      {
        System.out.println("All " + m[i][j] + "s on row " + i);
        row = true;
      }
    }
    //Column
    for(int i=0; i<size;i++)
    {
      letitbe = true;
      for (j =0;j<size-1;j++)
      {
        if (m[j][i] != m[j+1][i]) letitbe = false;
      }
      if (letitbe)
      {
        System.out.println("All " + m[j][i] + "s on column " + i);
        column = true;
      }
      
    }
    //Major diagonal, there is only one eh?
    letitbe = true;
    for (int  i=0;i<size-1;i++)
    {
      if (m[i][i]!= m[i+1][i+1]) letitbe = false;
    }
    if (letitbe)
    {
      System.out.println("All " + m[0][0] + "s on major diagonal");
      major = true;
    }
    
    letitbe = true;
    for (int  i=0;i<size-1;i++)
    {
      if (m[i][size-i-1]!= m[i+1][size-i-1-1]) letitbe = false;
    }
    if (letitbe)
    {
      System.out.println("All " + m[0][size-1] + "s on sub-diagonal");
      sub = true;
    }
  
    if ( column == false) System.out.println("No same numbers on a column");
    if ( row == false) System.out.println("No same numbers on a row");
    if ( major == false) System.out.println("No same numbers on the major diagonal");
    if ( sub == false) System.out.println("No same numbers on the sub-diagonal");
