hashcode java code example

Example 1: java hashcode

@Overridepublic int hashCode() {    int hash = 7;    hash = 31 * hash + (int) id;    hash = 31 * hash + (name == null ? 0 : name.hashCode());    hash = 31 * hash + (email == null ? 0 : email.hashCode());    return hash;}

Example 2: Java array hashcode

java.util.Arrays.hashCode(new int[1]) // for one dimensional arrays
java.util.Arrays.deepHashCode(new int[1][1]) // for mutli-dimensional arrays
