  下例中用到了前面提到的数据类型,并通过屏幕显示它们的值。


  public class SimpleTypes{


  public static void main( String args[] ){


  byte b=0x55;


  short s=0x55ff;


  int i=1000000;


  long l=0xfffL;


  char c='c';


  float f=0.23F;


  double d=0.7E-3;


  boolean bool=true;


  System.out.println("b = "+b);


  System.out.println("s = "+s);


  System.out.println("i = "+i);


  System.out.println("c = "+c);


  System.out.println("f = "+f);


  System.out.println("d = "+d);


  System.out.println("bool = "+bool);


  }


  }


  编译并运行该程序,输出结果为:


  C:\>java SimpleTypes


  b = 85


  s = 22015


  i = 1000000


  l = 4095


  c = c


  f = 0.23


  d = 0.0007


  bool = true
