Trouble with a matrix constructor

Question

im trying to make a constructor that creates a matrix based on a matrix that the user inputs, so i have this so far
public Matrices(int matriz[][])
        int numElements1 = matriz.length;
        int numElements2 = matriz[0].length;
        matrix = new int[numElements1][numElements2];
        for (int i = 0; i < numElements1; i++){
            for (int j = 0; j < numElements2; j++){
            matrix[i][j] = matriz[i][j];
    }im sure the problem is in the for but dunno what
when i try creating one, it says ArrayIndexOutOfBoundsException
help please

Answer 1

public Matrices(int matriz[][])
        int numElements1 = matriz.length;
        int numElements2 = matriz[0].length;
        matrix = new int[numElements1][numElements2];
        if (numElements1>numElements2)
            for (int i = 0; i < numElements1; i++){
                for (int j = 0; j < numElements2; j++){
                    matrix[i][j] = matriz[i][j];
        }else{
            for (int i = 0; i < numElements2; i++){
                for (int j = 0; j < numElements1; j++){
                    matrix[i][j] = matriz[i][j];
    }would this work??'
