The minimum value of Integer in Java is: -2147483648 综上所述,Java中Integer类型的最小值是-2147483648,可以通过Integer.MIN_VALUE来获取这个值。
从JDK1.0开始,Integer中就定义了MIN_VALUE和MAX-VALUE两个常量: /** * A constant holding the minimum value an {@code int} can * have, -231. */ public static final int MIN_VALUE = 0x80000000; /** * A constant holding the maximum value an {@code int} can * have, 231-1. */ pub...
* A constant holding the minimum value an {@code int} can * have, -231. */publicstaticfinal intMIN_VALUE=0x80000000;/** * A constant holding the maximum value an {@code int} can * have, 231-1. */publicstaticfinal intMAX_VALUE=0x7fffffff; 这两个范围大家经常用,一般不会出现问题。
