```java
public class Main {

    public static void main(String[] args) {
        // Bitwise OR (1 | 0 = 1)
        System.out.print("OR: " + Integer.toString(12, 2));          //   00001100
        System.out.print(" " + Integer.toString(25, 2));             // | 00011001
        System.out.print(" " + Integer.parseInt("00011101", 2));     // = 00011101
        System.out.println(" " + (12 | 25));

        // Bitwise AND (1 & 0 = 0) - (1 & 1 = 1)
        System.out.print("\nAND: " + Integer.toString(12, 2));        //   00001100
        System.out.print(" " + Integer.toString(25, 2));              // & 00011001
        System.out.print(" " + Integer.parseInt("00001000", 2));      // = 00001000
        System.out.println(" " + (12 & 25));

        // Bitwise XOR (1 & 0 = 1) - (1 & 1 = 0)
        System.out.print("\nAND: " + Integer.toString(12, 2));        //   00001100
        System.out.print(" " + Integer.toString(25, 2));              // ^ 00011001

        System.out.println(" " + (12 ^ 25));

        // Bitwise Complement (1 -> 0) - (0 -> 1), ~n = -(n + 1)
        System.out.print("\nComp: " + Integer.toString(35, 2));       //   00100011
        System.out.print(" " + Integer.parseInt("11011100", 2));      // = 11011100 -> result 220. why? its because binary also equal to -36
        System.out.println(" " + (~35));

        // Bitwise Left Shift - bit move to left
        System.out.print("\nLS: " + Integer.toString(35, 2));         //   00100011
        System.out.print(" " + Integer.parseInt("01000110", 2));      // = 01000110
        System.out.println(" " + (35 << 1));

        // Bitwise Signed Right Shift - bit move to right
        System.out.print("\nSRS: " + Integer.toString(35, 2));        //   00100011
        System.out.print(" " + Integer.parseInt("00010001", 2));      // = 00010001
        System.out.println(" " + (35 >> 1));

        // Bitwise Unigned Right Shift - bit move to right, leftmost position is filled with 0 instead of the sign bit.
        System.out.print("\nURS: " + Integer.toString(35, 2));        //   00100011
        System.out.print(" " + Integer.parseInt("00010001", 2));      // = 00010001
