Java 基本数据类型最大值极限和最小值

public static void main(String[] args){
    //Float
    System.out.println("Float.MIN_VALUE = " + Float.MIN_VALUE);
    System.out.println("Float.MIN_NORMAL = " + Float.MIN_NORMAL);
    System.out.println("Float.MAX_VALUE = " + Float.MAX_VALUE);    
    //Integer
    System.out.println("Integer.MIN_VALUE = " + Integer.MIN_VALUE);
    System.out.println("Integer.MAX_VALUE = " + Integer.MAX_VALUE);
    //Double
    System.out.println("Double.MAX_VALUE = " + Double.MAX_VALUE);
    System.out.println("Double.MIN_VALUE = " + Double.MIN_VALUE);
    //Long
    System.out.println("Long.MIN_VALUE = " + Long.MIN_VALUE);
    System.out.println("Long.MAX_VALUE = " + Long.MAX_VALUE);    

}

控制台输出结果如下:

Integer.MIN_VALUE = -2147483648
Integer.MAX_VALUE = 2147483647
Long.MIN_VALUE = -9223372036854775808
Long.MAX_VALUE = 9223372036854775807
Float.MIN_VALUE = 1.4E-45
Float.MIN_NORMAL = 1.17549435E-38
Float.MAX_VALUE = 3.4028235E38
Double.MAX_VALUE = 1.7976931348623157E308
Double.MIN_VALUE = 4.9E-324
