Java 中 LinkedBlockingDeque toString()方法
原文:https://www . geeksforgeeks . org/linkedblockingreque-tostring-method-in-Java/
的 toString() 方法将链接锁定请求返回该集合的字符串表示形式。字符串表示由集合元素的列表组成，这些元素按照迭代器返回的顺序排列，用方括号括起来(“[]”)。相邻的元素由字符、“(逗号和空格)分隔。元素被转换为字符串，如字符串值(对象)。
语法:
public String toString()
参数:此方法不接受任何参数。
返回:该方法返回该集合的字符串表示形式。
以下程序说明了链接锁定请求的到字符串()方法:
程序 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]
程序二:
// 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]
