LinkedBlockingDeque的clear()方法将擦除LinkedBlockingDeque容器中存在的所有元素。调用该函数后,容器将变为空。
用法:
public void clear()
参数:此方法不接受任何参数
返回值:此方法不返回任何内容。
以下示例程序旨在说明LinkedBlockingDeque的clear()方法:
示例1:
// Java Program Demonstrate clear()
// method of LinkedBlockingDeque
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
// 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);
// before using erase() function
System.out.println("Linked Blocking Deque: " + LBD);
LBD.clear();
// after using erase() function
System.out.println("Linked Blocking Deque: " + LBD);
}
}
输出:
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] Linked Blocking Deque: []
示例2:
// Java Program Demonstrate clear()
// method of LinkedBlockingDeque
// when the list contains characters
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
// create object of LinkedBlockingDeque
LinkedBlockingDeque<String> LBD
= new LinkedBlockingDeque<String>();
// Add numbers to end of LinkedBlockingDeque
LBD.add("1");
LBD.add("2");
LBD.add("3");
LBD.add("4");
// before using erase() function
System.out.println("Linked Blocking Deque: " + LBD);
LBD.clear();
// after using erase() function
System.out.println("Linked Blocking Deque: " + LBD);
}
}
输出:
Linked Blocking Deque: [1, 2, 3, 4] Linked Blocking Deque: []
