Java位集 |和
先决条件: Java BitSet |设置 1
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。
执行此目标位集与参数位集的逻辑与。修改此位集,以便当且仅当它最初都具有值 true 并且位集参数中的相应位也具有值 true 时,其中的每个位都具有值 true。
句法
public void and(BitSet set);
例子:
Input :
set1 : {1, 2, 4}
set2 : {2, 3, 4}
Output : After performing st1.and(set2)
set2 : {2, 4}
程序:
Java
// Java program illustrating Bitset Class constructors.
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.and(bs1);
// bs2 set after Performing AND
System.out.println("\nAfter AND operation : ");
System.out.println(bs2);
}
}
输出:
bs1 : {0, 1, 2, 4}
bs2 : {1, 2, 3, 4, 5, 6}
After AND operation :
{1, 2, 4}
