Java 中的位集等于()方法，示例
原文:https://www . geesforgeks . org/bitset-equals-method-in-Java-with-examples/
Java BitSet 类的 equals()方法用于检查两个 BitSet 之间的相等性。它验证作为参数传递的一个集合的元素是否等于这个集合的元素。如果位集匹配 else false，则方法返回 true。
语法:
Bit_Set1.equals(Bit_Set2)
参数:该方法接受一个位组类型的参数位组 2 ，并引用要用该位组检查其相等性的组。
返回值:如果两个对象集相等，则方法返回真，否则返回假。
下面的程序说明了 BitSet equals()方法在 Java 中的工作原理。 节目一:
// Java code to illustrate equals()
import java.util.*;
public class BitSet_Demo {
public static void main(String args[])
{
// Creating an empty BitSet
BitSet bit_set1 = new BitSet();
BitSet bit_set2 = new BitSet();
// Use set() method to add elements into the Set
bit_set1.set(40);
bit_set1.set(25);
bit_set1.set(80);
bit_set1.set(95);
bit_set1.set(5);
// Use set() method to add elements into the Set
bit_set2.set(25);
bit_set2.set(40);
bit_set2.set(5);
bit_set2.set(95);
bit_set2.set(80);
// Displaying the BitSets
System.out.println("First BitSet: " + bit_set1);
System.out.println("Second BitSet: " + bit_set2);
// Checking for equality
System.out.println("Are the sets equal? "
+ bit_set1.equals(bit_set2));
}
}
Output:
First BitSet: {5, 25, 40, 80, 95}
Second BitSet: {5, 25, 40, 80, 95}
Are the sets equal? true
程序 2:
// Java code to illustrate equals()
import java.util.*;
public class BitSet_Demo {
public static void main(String args[])
{
// Creating an empty BitSet
BitSet bit_set1 = new BitSet();
BitSet bit_set2 = new BitSet();
// Use set() method to add elements into the Set
bit_set1.set(40);
bit_set1.set(25);
bit_set1.set(80);
bit_set1.set(95);
bit_set1.set(5);
// Use set() method to add elements into the Set
bit_set2.set(10);
bit_set2.set(20);
bit_set2.set(30);
bit_set2.set(40);
bit_set2.set(50);
// Displaying the BitSets
System.out.println("First BitSet: " + bit_set1);
System.out.println("Second BitSet: " + bit_set2);
// Checking for equality
System.out.println("Are the sets equal? "
+ bit_set1.equals(bit_set2));
}
}
Output:
First BitSet: {5, 25, 40, 80, 95}
Second BitSet: {10, 20, 30, 40, 50}
Are the sets equal? false
