Java By Example: Values

Java has various value types including String , Integer, Double, Boolean, etc. Here are a few basic examples.

The usage of these data types are shown in the below code block

class Values {
  public static void main(String[] args) {

    // Strings, that can be added together with +.
    System.out.println("Java" + " " + "Lang"); 

    // Integer and Double
    Integer sum = 1+1;
    Double division = 7.0/3.0;
    System.out.println("1+1 = " + sum);
    System.out.println("7.0/3.0 =" + division);

    //Booleans, with boolean operators as you’d expect.
    System.out.println(true && false);
    System.out.println(true || false); 
    System.out.println(!true);
  }
}

Below are the commands and output.
