Java入门教程:数据类型举例

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
