Java LinkedBlockingDeque toString()用法及代码示例


LinkedBlockingDeque的toString()方法返回此集合的字符串表示形式。字符串表示形式包括一个集合元素的列表,这些元素按其迭代器返回的顺序排列,并括在方括号(“[]”)中。相邻元素之间用字符“,”(逗号和空格)分隔。元素通过String.valueOf(Object)转换为字符串。

用法:

public String toString()

参数:此方法不接受任何参数。


返回值:此方法返回此集合的字符串表示形式。

以下示例程序旨在说明LinkedBlockingDeque的toString()方法:

示例1:

// Java Program Demonstrate toString() 
// method of LinkedBlockingDeque 
  
import java.util.concurrent.LinkedBlockingDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
  
    { 
  
        // create object of LinkedBlockingDeque 
        LinkedBlockingDeque<Integer> LBD 
            = new LinkedBlockingDeque<Integer>(); 
  
        // Add numbers to end of LinkedBlockingDeque 
        LBD.add(7855642); 
        LBD.add(35658786); 
        LBD.add(5278367); 
        LBD.add(74381793); 
  
        // Print the queue 
        System.out.println("Linked Blocking Deque: " + LBD); 
  
        System.out.println("LBD in string " + LBD.toString()); 
    } 
}
输出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
LBD in string [7855642, 35658786, 5278367, 74381793]

示例2:

// Java Program Demonstrate toString() 
// method of LinkedBlockingDeque 
  
import java.util.concurrent.LinkedBlockingDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
  
    { 
  
        // create object of LinkedBlockingDeque 
        LinkedBlockingDeque<String> LBD 
            = new LinkedBlockingDeque<String>(); 
  
        // Add numbers to end of LinkedBlockingDeque 
        LBD.add("geeks"); 
        LBD.add("sudo"); 
        LBD.add("gate"); 
        LBD.add("gopal"); 
  
        // Print the queue 
        System.out.println("Linked Blocking Deque: " + LBD); 
  
        System.out.println("LBD in string " + LBD.toString()); 
    } 
}
输出:
Linked Blocking Deque: [geeks, sudo, gate, gopal]
LBD in string [geeks, sudo, gate, gopal]
