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
