Java LinkedBlockingDeque equals()用法及代碼示例

java.util.LinkedBlockingDeque類的equals()方法用於比較指定對象與此LinkedBlockingDeque是否相等。當且僅當指定對象也是LinkedBlockingDeque，且兩個LinkedBlockingDeques具有相同的大小，並且兩個LinkedBlockingDeques中所有對應的元素對相等時，才返回true。 (如果(e1 == null？e2 == null：e1.equals(e2))，則兩個元素e1和e2相等。)換句話說，如果兩個LinkedBlockingDeques包含相同順序的相同元素，則它們被定義為相等。。

用法:

public boolean equals(Object o)

參數：此方法將對象o作為要與此LinkedBlockingDeque進行相等性比較的參數。

返回值：如果指定對象等於此LinkedBlockingDeque，則此方法返回true。

以下示例說明了LinkedBlockingDeque.equals()方法：

示例1:

// Java Program Demonstrate equals() 
// 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> LBD1 
            = new LinkedBlockingDeque<Integer>(); 
  
        // Add numbers to end of LinkedBlockingDeque 
        LBD1.add(7855642); 
        LBD1.add(35658786); 
        LBD1.add(5278367); 
        LBD1.add(74381793); 
  
        System.out.println("Linked Blocking Deque 1: " + LBD1); 
  
        // create another object of LinkedBlockingDeque 
        LinkedBlockingDeque<String> LBD2 
            = new LinkedBlockingDeque<String>(); 
  
        // Add numbers to end of LinkedBlockingDeque 
        LBD2.add("1"); 
        LBD2.add("2"); 
        LBD2.add("3"); 
        LBD2.add("4"); 
  
        System.out.println("Linked Blocking Deque 2: " + LBD2); 
  
        // using equals() function 
        System.out.println("Are both Linked Blocking Deque equal: "
                           + LBD1.equals(LBD2)); 
    } 
}

輸出：

Linked Blocking Deque 1: [7855642, 35658786, 5278367, 74381793]
Linked Blocking Deque 2: [1, 2, 3, 4]
Are both Linked Blocking Deque equal: false

示例2:

// Java Program Demonstrate equals() 
// 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> LBD1 
            = new LinkedBlockingDeque<String>(); 
  
        // Add numbers to end of LinkedBlockingDeque 
        LBD1.add("1"); 
        LBD1.add("2"); 
        LBD1.add("3"); 
        LBD1.add("4"); 
  
        System.out.println("Linked Blocking Deque 1: " + LBD1); 
  
        // using equals() function 
        System.out.println("Is LBD1 equal to LBD1: "
                           + LBD1.equals(LBD1)); 
    } 
}

輸出：

Linked Blocking Deque 1: [1, 2, 3, 4]
Is LBD1 equal to LBD1: true
