Java4android "4" Java variables

Java variables are divided into:

1: Basic type:

Character type, Boolean, numeric type.

2: Reference type (temporarily not seen)

By the way, familiarize yourself with this code.

public class test{

public static void Main (String args[]) {

System.out.println ("Test");

}

Attention:

1 This test and name should match the Test.java.

2 compile, javac Test.java suffix can not be less, but the execution of the time is Java Test. No test.class.

The name of the 3 variable is legal if it starts with a letter underlined dollar sign.
