java bitset

BitSet类或()方法 (BitSet Class or() method)

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

  or()方法在java.util包中可用。

• or() method is used to perform logical OR between this BitSet and the given BitSet(bs). This BitSet is updated when either this BitSet bit holds the value true or the given BitSet(bs) corresponding bit hold the value true.

  or()方法用于在此BitSet与给定的BitSet(bs)之间执行逻辑或。 当任此BitSet位保持值为true或给定的位集合(BS)对应位持有true值此BitSet被更新。

• or() 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.

  or()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。

• or() method does not throw an exception at the time of performing logical or operation.

  or()方法在执行逻辑或操作时不会引发异常。

Syntax:

句法：

    public void or(BitSet bs);

Parameter(s):

参数：

• BitSet bs – represents a bit set.

  BitSet bs –表示一个位集。

Return value:

返回值：

The return type of this method is void, it returns nothing.

此方法的返回类型为void ，不返回任何内容。

Example:

例：

// Java program to demonstrate the example 
// of void or(BitSet bs) method of BitSet.
import java.util.*;
public class OrOfBitSet {
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 or() method is to perform
// logical OR between two BitSet(i.e. It returns
// all values set in any bitset )
bs1.or(bs2);
// Display BitSet 1
System.out.println("bs1.or(bs2) : " + bs1);
}
}

Output

输出量

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