java语言求各个数据类型的最值

public class value{
    public static void main(String[] args) {
        System.out.println("Intager Max:"+Integer.MAX_VALUE);
        System.out.println("Intager Min:"+Integer.MIN_VALUE);
        System.out.println("Long Max:"+Long.MAX_VALUE);
        System.out.println("Long Min:"+Long.MIN_VALUE);
        System.out.println("Short Max:"+Short.MAX_VALUE);
        System.out.println("Short Min:"+Short.MIN_VALUE);
        System.out.println("Float Max:"+Float.MAX_VALUE);        //标准化的最大值
        System.out.println("Float.MIN_NORMAL:"+Float.MIN_NORMAL);//标准化的最小值
        System.out.println("Float Min:"+Float.MIN_VALUE);        //非标准化的最小值
        System.out.println("Double Max:"+Double.MAX_VALUE);
        System.out.println("Double Min:"+Double.MIN_VALUE);
    }
}
