Java BigInteger negate()用法及代碼示例


先決條件:BigInteger基礎
java.math.BigInteger.negate()方法返回一個BigInteger,其值為(-this)。 negate()方法將更改BigInteger的單個位。

用法:

public BigInteger negate()

參數:該方法不接受任何參數。


返回值:該方法返回(-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 

以下示例程序旨在說明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); 
    } 
}
輸出:
Result of negate operation on 2300 is -2300
