    I'm working on a program that requires redefining the toString method to display the values of a 2-dimensional Matrix, instead of their memory address. Then, redefine the equals method so the Matrix objects are compared correctly.
    Here is what I've tried so far:
    
 import java.util.Random;  public class TextLab09 { 	public static void main(String args[]) 	{ 		System.out.println("TextLab09\n\n"); 		Matrix m1 = new Matrix(3,4,1234); 		Matrix m2 = new Matrix(3,4,1234); 		Matrix m3 = new Matrix(3,4,4321); 		System.out.println("Matrix m1\n"); 		System.out.println(m1+"\n\n"); 		System.out.println("Matrix m2\n"); 		System.out.println(m2+"\n\n"); 		System.out.println("Matrix m3\n"); 		System.out.println(m3+"\n\n"); 		if (m1.equals(m2)) 			System.out.println("m1 is equal to m2\n"); 		else 			System.out.println("m1 is not equal to m2\n"); 		if (m1.equals(m3)) 			System.out.println("m1 is equal to m3\n"); 		else 			System.out.println("m1 is not equal to m3\n"); 	} }  class Matrix { 	private int rows; 	private int cols; 	private int mat[][];  	public Matrix(int rows, int cols, int seed) 	{ 		this.rows = rows; 		this.cols = cols; 		mat = new int[rows][cols]; 		Random rnd = new Random(seed); 		for (int r = 0; r < rows; r ++) 			for (int c = 0; c < cols; c++) 			{ 				int randomInt = rnd.nextInt(90) + 10; 				mat[r][c] = randomInt; 			} 	}    public String toString() { 	int randomint = Integer.parseInt(randomInt); 	 	return "[" + mat + "]"; 	 }    public boolean equals (Matrix that)    { 	   return 	this.rows ==(that.rows)  	&&    	    this.cols    	==  that.cols;  		  	         } } 

    I'm not sure as to what part of the matrix method I need to convert to an int value, or if I should use valueOf instead of parseInt?
    Thanks!

    Your easiest (but not necessarily finest) option for toString would be to use java.util.Arrays.deepToString

    equals could be done using java.util.Arrays.equal on each row
