Here´s a code: https://code.sololearn.com/cGBdMNf5dTqJ I hope this isn't your homework. But your teacher will find out anyway, that you didn´t do it on your own if it is :D

What exactly do you want to do? Do you want to count, how often every single element of array2 is contained in array1?

@Kenyatta 😂 I can imagine! I just hope he has to explain the code and why the utility classes I put there are used.

use double for each loops, or double iterators

FOR 1D ARRAY int count =0; for(int x = 0;x<array1.length;x++){ for(int y=0;y<array2.length;y++){ if(array1[x].equals(array2[y])){ count++; } }}

This is static code which counts a number of times array2 present in array1 but I want a dynamic code for the same i.e. even if change int array2[][]={{10,20,30},{10,20,40}} it should show proper count This is a static code: public static void main(String[] args) { int array1[][]= {{10,20,30,40,50,60},{10,20,40,50,70,60},{10,20,30,40,50,60},{60,70,50,40,10,20},{80,90,70,60,10,20},{60,70,50,40,10,20}}; int array2[][]= {{10,20},{10,20}}; for (int i = 0; i < array1.length; i++) { for (int j = 0; j < array1[0].length; j++) { System.out.print(array1[i][j]+"\t"); } System.out.println(); } int cnt=0; for (int i = 0; i < array1.length-1; i++) { for (int j = 0; j < array1[0].length-1; j++) { for (int k = 0; k < array2.length-1; k++) { for (int l = 0; l < array2.length-1; l++) { if((array1[i][j]==array2[k][l])&&(array1[i][j+1]==array2[k][l+1])&&(array1[i+1][j]==array2[k+1][l])&&(array1[i+1][j+1]==array2[k+1][l+1])) { cnt++; } } } } } System.out.println("\nCount for array2 present in array1 is: "+cnt++); } please give me a dynamic code for same
