java bitset

BitSet類或()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與給定的BitSet(bs)之間執行邏輯或。 當任此BitSet位保持值為true或給定的位集合(BS)對應位持有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()方法是一種非靜態方法，因此可以通過類對象進行訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

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

  or()方法在執行邏輯或操作時不會引發異常。

Syntax:

句法：

    public void or(BitSet bs);

Parameter(s):

參數：

• BitSet bs – represents a bit set.

  BitSet bs –表示一個位集。

Return value:

返回值：

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

此方法的返回類型為void ，不返回任何內容。

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

輸出量

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