Java LinkedBlockingDeque toString()用法及代碼示例


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個集合元素的列表,這些元素按其迭代器返回的順序排列,並括在方括號(“[]”)中。相鄰元素之間用字符“,”(逗號和空格)分隔。元素通過String.valueOf(Object)轉換為字符串。

用法:

public String toString()

參數:此方法不接受任何參數。


返回值:此方法返回此集合的字符串表示形式。

以下示例程序旨在說明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()); 
    } 
}
輸出:
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()); 
    } 
}
輸出:
Linked Blocking Deque: [geeks, sudo, gate, gopal]
LBD in string [geeks, sudo, gate, gopal]
