先决条件：BigInteger基础
的java.math.BigInteger.negate()方法返回一个BigInteger，其值为(-this)。 negate()方法将更改BigInteger的单个位。
用法:
public BigInteger negate()
参数：该方法不接受任何参数。
返回值：该方法返回(-this)的操作。
例子：
Input: value = 2300
Output: -2300
Explanation:
Binary signed 2's complement of 2300 = 0000100011111100
Singed bit are 0000
change sing bit to 1111
so negate of 0000100011111100 in signed 2's complement is 1111011100000100
Decimal value = -2300.
Input: value = 567689
Output: -567689
以下示例程序旨在说明BigInteger的negate()方法。
/*
*Program Demonstrate negate() method of BigInteger
*/
import java.math.*;
public class GFG {
public static void main(String[] args)
{
// Create BigInteger object
BigInteger biginteger = new BigInteger("2300");
// Call negate() method to find -this
BigInteger finalvalue = biginteger.negate();
String result = "Result of negate operation on " +
biginteger + " is " + finalvalue;
// Prints result
System.out.println(result);
}
}
输出：
Result of negate operation on 2300 is -2300
