Java 程序将正整数转换为负数,将负数转换为正数
要将正整数转换为负数并反之亦然,请使用按位取反运算符。
让我们首先初始化一个正整数 −
int positiveVal = 200;
现在,让我们将其转换为负数 −
int negativeVal = (~(positiveVal - 1));
现在,假设我们有以下负整数 −
int negativeVal = -300;
以下内容将负数转换为正整数 −
positiveVal = ~(negativeVal - 1);
示例
public class Demo { public static void main(String[] args) throws java.lang.Exception { int positiveVal = 100; int negativeVal = (~(positiveVal - 1)); System.out.println("Result: Positive value converted to Negative = "+negativeVal); positiveVal = ~(negativeVal - 1); System.out.println("Actual Positive Value = "+positiveVal); negativeVal = -200; System.out.println("Actual Negative Value = "+negativeVal); positiveVal = ~(negativeVal - 1); System.out.println("Result: Negative value converted to Positive = "+positiveVal); } }
输出
Result: Positive value converted to Negative = -100 Actual Positive Value = 100 Actual Negative Value = -200 Result: Negative value converted to Positive = 200
