Java位集 |异或

BitSet 是在Java.util 包中定义的一个类。它创建一个由布尔值表示的位数组。

句法

public void xor(BitSet set);

解释:
该方法执行逻辑 XOR ,使得在 BitSet 中,当且仅当该位最初具有值 true 并且参数中的相应位具有值 false 时设置一个位,反之亦然。

例子:

Input : 
set1 : {1, 2, 4}
set2 : {2, 3, 4}

Output :
After performing st1.xor(set2)
set2 : {1, 3}

程序:

Java
// Java program illustrating Bitset Class Function.
import java.util.*;
public class GFG {
    public static void main(String[] args)
    {
        // Constructors of BitSet class
        BitSet bs1 = new BitSet();
        BitSet bs2 = new BitSet(6);
 
        /* set is BitSet class method
        explained in next articles */
        bs1.set(0);
        bs1.set(1);
        bs1.set(2);
        bs1.set(4);
 
        // assign values to bs2
        bs2.set(4);
        bs2.set(6);
        bs2.set(5);
        bs2.set(1);
        bs2.set(2);
        bs2.set(3);
 
        // Printing the 2 Bitsets
        System.out.println("bs1 : " + bs1);
        System.out.println("bs2 : " + bs2);
 
        // Performing logical AND
        // on bs2 set with bs1
        bs2.xor(bs1);
 
        // bs2 set after Performing AND
        System.out.println("After Performing XOR :");
        System.out.println(bs2);
    }
}


输出:
bs1 : {0, 1, 2, 4}
bs2 : {1, 2, 3, 4, 5, 6}
After Performing XOR :
{0, 3, 5, 6}
