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

*  **toString() method** is available in java.util package.
    
    **toString()方法**在java.util包中可用。
 *  **toString() method** is used to represent string denotation of this BitSet so the representation would be from the first index to the last index separated by ',' or whitespace "" and surrounded by curly braces \{\}.
    
    **toString()方法**用于表示此BitSet的字符串表示形式，因此表示形式是从第一个索引到最后一个索引，并用'，'或空格“”分隔，并用花括号\{\}包围。
 *  **toString() 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.
    
    **toString()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。
 *  **toString() method** does not throw an exception at the time of string representation of this BitSet.
    
    在此BitSet的字符串表示形式时， **toString()方法**不会引发异常。

**参数：**

*  It does not accept any parameter.

**返回值：**

The return type of this method is String, it returns string representation of this BitSet.

该方法的返回类型为String ，它返回此BitSet的字符串表示形式。

**Example:**

**例：**

// Java program to demonstrate the example 
    // of String toString() method of BitSet.
    
    import java.util.*;
    
    public class ToStringOfBitSet {
        
        public static void main(String[] args) {
        
            // create an object of BitSet
            BitSet bs = new BitSet(10);
    
            // By using set() method is to set
            // the values in BitSet 
            bs.set(10);
            bs.set(20);
            bs.set(30);
            bs.set(40);
            bs.set(50);
    
            // Display Bitset
            System.out.println("bs: " + bs);
    
            // By using toString() method is to 
            // string representation of this BitSet
            String s = bs.toString();
    
            // Display s
            System.out.println("bs.toString(): " + s);
        }
    }

**Output**

**输出量**

bs: {10, 20, 30, 40, 50}
    bs.toString(): {10, 20, 30, 40, 50}
