java bitset

## BitSet类的equals()方法 **(**BitSet Class equals() method**)** ##

*  **equals() method** is available in java.util package.
    
    **equals()方法**在java.util包中可用。
 *  **equals() method** is used to check whether this object against the given object is the same or not.
    
    **equals()方法**用于检查针对给定对象的此对象是否相同。
 *  **equals() 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.
    
    **equals()方法**是一种非静态方法，因此可通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。
 *  **equals() method** does not throw an exception at the time of comparing two BitSet objects.
    
    比较两个BitSet对象时， **equals()方法**不会引发异常。

**Syntax:**

**句法：**

public boolean equals(Object o);

**Parameter(s):**

**参数：**

*  Object o – represents the object to check equality with the object.
    
    对象o –表示要检查与对象是否相等的对象。

**Return value:**

**返回值：**

The return type of this method is boolean, it returns *true* when the given BitSet object has same set of bits with this BitSet object otherwise it returns *false*.

此方法的返回类型为boolean ，当给定的BitSet对象与此BitSet对象具有相同的位集时返回*true* ，否则返回*false* 。

**Example:**

**例：**

// Java program to demonstrate the example 
    // of boolean equals(Object o) method of BitSet.
    
    import java.util.*;
    
    public class EqualsOfBitSet {
        
        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);
    
            // 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 BitSet2
            System.out.println("bs1: " + bs1);
            System.out.println("bs2: " + bs2);
    
            // By using equals(Object) method is to check whether
            // the given bitset has same set of bits with
            // the against BitSet object or not
            boolean status = bs1.equals(bs2);
    
            // Display status
            System.out.println("bs1.equals(bs2): " + status);
        }
    }

**Output**

**输出量**

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