java.util.AbstractSequentialList类的equals()方法用于检查此AbstractSequentialList对象是否等于作为参数传递的对象。此方法返回一个声明相同的布尔值。
用法:
public boolean equals(Object o)
参数:此方法将对象o作为要与该列表进行相等性比较的参数。
返回值:如果指定对象等于此列表,则此方法返回true。
以下示例说明了equals()方法。
范例1:
// Java program to demonstrate equals()
// method of AbstractSequentialList
import java.util.*;
public class GFG {
public static void main(String[] argv)
{
// Creating object of AbstractSequentialList<String>
AbstractSequentialList<String>
arrlist1 = new LinkedList<String>();
// Populating arrlist1
arrlist1.add("A");
arrlist1.add("B");
arrlist1.add("C");
arrlist1.add("D");
arrlist1.add("E");
// print arrlist1
System.out.println("First AbstractSequentialListlist:"
+ arrlist1);
// Creating another object of AbstractSequentialList<String>
AbstractSequentialList<String>
arrlist2 = new LinkedList<String>();
// Populating arrlist2
arrlist2.add("A");
arrlist2.add("B");
arrlist2.add("C");
arrlist2.add("D");
arrlist2.add("E");
// print arrlist2
System.out.println("Second AbstractSequentialList:"
+ arrlist2);
// comparing first AbstractSequentialList to another
// using equals() method
boolean value
= arrlist1.equals(arrlist2);
// print the value
System.out.println("Are both list equal:"
+ value);
}
}
输出:
First AbstractSequentialListlist:[A, B, C, D, E] Second AbstractSequentialList:[A, B, C, D, E] Are both list equal:true
范例2:
// Java program to demonstrate equals()
// method of AbstractSequentialList
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
// Creating object of AbstractSequentialList
AbstractSequentialList<Integer>
arrlist1 = new LinkedList<Integer>();
// Populating arrlist1
arrlist1.add(10);
arrlist1.add(20);
arrlist1.add(30);
arrlist1.add(40);
arrlist1.add(50);
// print arrlist1
System.out.println("First AbstractSequentialListlist:"
+ arrlist1);
// Creating another object of AbstractSequentialList
AbstractSequentialList<Integer>
arrlist2 = new LinkedList<Integer>();
// Populating arrlist2
arrlist2.add(10);
arrlist2.add(20);
arrlist2.add(30);
// print arrlist2
System.out.println("Second AbstractSequentialList:"
+ arrlist2);
// comparing first AbstractSequentialList to another
// using equals() method
boolean value = arrlist1.equals(arrlist2);
// print the value
System.out.println("Are both list equal:"
+ value);
}
}
输出:
First AbstractSequentialListlist:[10, 20, 30, 40, 50] Second AbstractSequentialList:[10, 20, 30] Are both list equal:false
