“&=” and “|=” are some of the less frequently used operators in java. These operators works same as “+=” and “-=” operators which we use regularly.

“&=” example

public static void main(String[] args) {
    boolean a = true;
    boolean b = false;
    boolean r1 = a&=b;
    boolean r2 = (a&b);
    // so a&=b –> a= (a&b)
    System.out.println(r1);
    System.out.println(r2);
}

similarly != works on the same way. Similarly we have “^=” also (XOR).

result:

false

false
