clone() method is available in java.util package.
clone()方法在java.util包中可用。
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。

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
