Java by Example: Core Value Types
|
Java has various value types including Strings, Integers, Floats, Booleans, etc. Here are a few basic examples. |
|
 
public class CoreValueTypes { |
|
public static void main(String[] args) { |
|
|
Strings, which can be added together with |
System.out.println("Java" + "Program");
|
|
Integers and floats. |
System.out.println("1+1 =", 1+1);
System.out.println("7.0/3.0 =", 7.0/3.0);
|
|
Booleans, with boolean operators as you'd expect. |
System.out.println(true && false);
System.out.println(true || false);
System.out.println(!true);
}
|
$ java CoreValueTypes JavaProgram 1+1 = 2 7.0/3.0 = 2.3333333333333335 false true false |
