The ArrayList class gets its equals() method from the AbstractList class:
public boolean equals(Object o)
An ArrayList is equal to another object if
the other object implements the List interface,
has the same size(), and
contains the same elements in the same positions.
import java.util.Arrays;
import java.util.List;
public class MainClass {
//from w w w . j a v a 2 s . com
public static void main(String[] a) {
List list = Arrays.asList(new String[] { "A", "B", "C", "D" });
List list2 = Arrays.asList(new String[] { "A", "B", "C" });
System.out.println(list.equals(list2));
}
}
运行结果如下:
【list】
