public void arraysEqual() {
  int[] arr1 = new int[20]; // initialized to 0
  int[] arr2 = new int[20]; // initialized to 0
  arr1.equals(arr2); // false
}

Compliant Solution

This compliant solution compares the content of two arrays using the two-argument Arrays.equals() method.

public void arrayContentsEqual() {
  int[] arr1 = new int[20]; // initialized to 0
  int[] arr2 = new int[20]; // initialized to 0
  Arrays.equals(arr1, arr2); // true
}

...

Compliant Solution

This compliant solution compares the array references using the reference equality operators ==.

public void arrayReferencesEqual(int[] arr1, int[] arr2) {
  arr1 = arr2; 
}

...

Risk Assessment

Using the equals() method or relational operators with the intention of comparing array contents produces incorrect results, which can lead to vulnerabilities.
