Java 中的 BitSet 克隆()方法,示例
原文:https://www . geesforgeks . org/bitset-clone-method-in-Java-with-examples/
clone()方法 Java.util.BitSet 类用于创建现有 BitSet 的副本。新的位集与现有的位集完全相同,只是先前位集的副本。
语法:
Bit_Set.clone()
参数:该方法不取任何参数。
返回值:该方法只是返回现有位集的另一个副本。
下面的程序说明了 BitSet clone()方法在 Java 中的工作原理。 节目一:
// Java code to illustrate clone()
import java.util.*;
public class BitSet_Demo {
public static void main(String args[])
{
// Creating an empty BitSet
BitSet init_bitset = new BitSet();
// Use set() method to add elements into the Set
init_bitset.set(10);
init_bitset.set(20);
init_bitset.set(30);
init_bitset.set(40);
init_bitset.set(50);
// Displaying the BitSet
System.out.println("Initial BitSet: " + init_bitset);
// Creating a new cloned set
BitSet cloned_set = new BitSet();
// Cloning the set using clone() method
cloned_set = (BitSet)init_bitset.clone();
// Displaying the new Set after Cloning
System.out.println("The new BitSet: " + cloned_set);
}
}
Output:
Initial BitSet: {10, 20, 30, 40, 50}
The new BitSet: {10, 20, 30, 40, 50}
程序 2:
// Java code to illustrate clone()
import java.util.*;
public class BitSet_Demo {
public static void main(String args[])
{
// Creating an empty BitSet
BitSet init_bitset = new BitSet();
// Use set() method to add elements into the Set
init_bitset.set(40);
init_bitset.set(25);
init_bitset.set(80);
init_bitset.set(95);
init_bitset.set(5);
// Displaying the BitSet
System.out.println("Initial BitSet: " + init_bitset);
// Creating a new cloned set
BitSet cloned_set = new BitSet();
// Cloning the set using clone() method
cloned_set = (BitSet)init_bitset.clone();
// Displaying the new Set after Cloning
System.out.println("The new BitSet: " + cloned_set);
}
}
Output:
Initial BitSet: {5, 25, 40, 80, 95}
The new BitSet: {5, 25, 40, 80, 95}
