java compare arrays for equality code example

Example 1: compare arrays java

import java.util.Arrays; 
class Test 
{ 
    public static void main (String[] args)  
    { 
        // inarr1 and inarr2 have same values 
        int inarr1[] = {1, 2, 3}; 
        int inarr2[] = {1, 2, 3};    
        Object[] arr1 = {inarr1};  // arr1 contains only one element 
        Object[] arr2 = {inarr2};  // arr2 also contains only one element 
        if (Arrays.equals(arr1, arr2)) 
            System.out.println("Same"); 
        else
            System.out.println("Not same"); 
    } 
}

Example 2: Java array equals

java.util.Arrays.equals(a, b) // narrow equals (values are compared with == and value.equals)
java.util.Arrays.deepEquals(a, b) // deep equals (recursively looks at nested arrays)
