java bitset

BitSet類和()方法 (BitSet Class and() method)

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

  and()方法在java.util包中可用。

• and() method is used to perform logical AND between two Bitset. This bit set is updated so that every bit holds the value true when and only when both bitsets holds the value true.

  and()方法用于在兩個Bitset之間執行邏輯與。 更新此位集，以便僅當且僅當兩個位集均都為真時，每個位才為真。

• and() 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.

  and()方法是一個非靜態方法，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。

• and() method does not throw an exception at the time of operating logical AND.

  and()方法在進行邏輯AND操作時不會引發異常。

Syntax:

句法：

public void and(Bitset bs);

Parameter(s):

參數：

• BitSet bs – represents a bit set (like an integer number).

  BitSet bs –表示一個位集(如整數)。

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 and() method of BitSet.import java.util.*;public class AndOfBitSet {public static void main(String[] args) {// create an object of two BitSetBitSet 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 BitSet2System.out.println("bs1 :" + bs1);System.out.println("bs2:" + bs2);// By using and() method is to perform// logical AND between two BitSet(i.e. It returns// Common values)bs1.and(bs2);// Display BitSet 1System.out.println("bs1.and(bs2) : " + bs1);} }

Output

輸出量

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