java 几种基本类型的长度值

package cn.edu.henu.test;public class DataLengthTest {public static void main(String[] args) {System.out.println("Integer: " + Integer.MIN_VALUE + " -> " + Integer.MAX_VALUE);System.out.println("Long: " + Long.MIN_VALUE + " -> " + Long.MAX_VALUE);System.out.println("Float: " + Float.MIN_VALUE + " -> " + Float.MAX_VALUE);System.out.println("Double: " + Double.MAX_VALUE + " -> " + Double.MIN_VALUE);}}

结果为

Integer: -2147483648 -> 2147483647
Long: -9223372036854775808 -> 9223372036854775807
Float: 1.4E-45 -> 3.4028235E38
Double: 1.7976931348623157E308 -> 4.9E-324
