Boolean Literals

Boolean literals are only two logical values that a boolean value can have, true and false.

The values of true and false cannot be converted to any numerical value.

The true literal in Java does not equal 1, nor does the false literal equal 0.

public class Main {
  public static void main(String[] argv) {
    boolean b = true;

    int i = b;

  }
}

If you try to compile the program, the following error message will be generated by compiler.

Main.java:5: incompatible types
found   : boolean
required: int
    int i = b;
            ^
