java bitset

BitSet类intersects()方法 (BitSet Class intersects() method)

• intersects() method is available in java.util package.

  intersects()方法在java.util包中可用。

• intersects() method is used to check the common number of bits set to true in both the BitSet [this BitSet and the given BitSet(bs)].

  intersects()方法用于检查BitSet [this BitSet和给定的BitSet(bs)]中设置为true的通用位数。

• intersects() method is a non-static method, so it is accessible with the class object and if we try to access the method with the class name then we will get an error.

  intersects()方法是一种非静态方法，因此可以通过类对象进行访问，如果尝试使用类名称访问该方法，则会收到错误消息。

• intersects() method does not throw an exception at the time of checking the common number of bits set to true in both the BitSet.

  在检查两个BitSet中都设置为true的通用位数时， intersects()方法不会引发异常。

Syntax:

句法：

    public boolean intersects(BitSet bs);

Parameter(s):

参数：

• BitSet bs – represents the BitSet to intersect with this BitSet.

  BitSet bs –表示要与此BitSet相交的BitSet。

Return value:

返回值：

The return type of this method is boolean, it returns true when the given BitSet(bs) has bits set to true and the same bits set to true in this BitSet otherwise it returns false.

这种方法的返回类型是布尔值 ，当给定的位集合(BS)具有设置为true比特，并在此BitSet设置为true，相同比特否则返回假 ，则返回true。

Example:

例：

// Java program to demonstrate the example
// of boolean intersects(BitSet bs) method of BitSet.
import java.util.*;
public class IntersectsOfBitSet {public static void main(String[] args) {// create an object of two BitSet
BitSet bs1 = new BitSet(10);
BitSet bs2 = new BitSet(10);
// By using set() method is to set
// the values in BitSet 1
bs1.set(10);
bs1.set(20);
bs1.set(30);
bs1.set(40);
bs1.set(50);
// By using set() method is to set
// the values in BitSet 2
bs2.set(60);
bs2.set(70);
bs2.set(50);
bs2.set(40);
bs2.set(30);
// Display Bitset1 and BitSet2
System.out.println("bs1: " + bs1);
System.out.println("bs2: " + bs2);
// By using intersects(BitSet) method is to check whether
// both the bitset has some common bits or not
boolean status = bs1.intersects(bs2);
// Display status
System.out.println("bs1.intersects(bs2): " + status);
}
}

Output

输出量

bs1: {10, 20, 30, 40, 50}
bs2: {30, 40, 50, 60, 70}
bs1.intersects(bs2): true
