System.out.println("Min Int = " + Math.abs(Byte.MIN_VALUE));
System.out.println("Min Long = " + Math.abs(Short.MIN_VALUE));
System.out.println("Min Int = " + Math.abs(Integer.MIN_VALUE));
System.out.println("Min Long = " + Math.abs(Long.MIN_VALUE));
输出：
Min Int = 128
Min Long = 32768
Min Int = -2147483648
Min Long = -9223372036854775808
为什么有正有负？
