• clone() method is used to clone this Bitset or in other words, this method is used to create a Bitset that is similar to this Bitset.

  clone()方法用于克隆此Bitset，换句话说，此方法用于创建与该Bitset相似的Bitset。

• clone() 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.

  clone()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。

  它不接受任何参数。

Return value:

返回值：

The return type of this method is Object, it returns cloned object of this bit set.

此方法的返回类型为Object ，它返回此位集的克隆对象。

Example:

例：

// Java program to demonstrate the example
// of Object clone() method of BitSet.
import java.util.*;
public class CloneOfBitSet {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);
// Display Bitset1 and BitSet2
System.out.println("bs1: " + bs1);
System.out.println("bs2: " + bs2);
// By using clone() method is to copy the
//e lements of BitSet1 to another BitSet2
bs2 = (BitSet) bs1.clone();
// Display BitSet 2
System.out.println("bs1.clone()  : " + bs2);
}
}

Output

输出量

bs1: {10, 20, 30, 40, 50}
bs2: {}
bs1.clone()  : {10, 20, 30, 40, 50}
