从Java LinkedHashSet获取键值对
要在Java中获取LinkedHashSet键值对，请使用entrySet()方法。
让我们首先创建LinkedHashSet并添加一些元素-
LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();
l.put("1", "Jack");
l.put("2", "Tom");
l.put("3", "Jimmy");
l.put("4", "Morgan");
l.put("5", "Tim");
l.put("6", "Brad");现在，获取一个键值对-
l.entrySet()
以下是从LinkedHashSet获取键值对的示例-
示例
import java.util.*;
public class Demo {
public static void main(String[] args) {
LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();
l.put("1", "Jack");
l.put("2", "Tom");
l.put("3", "Jimmy");
l.put("4", "Morgan");
l.put("5", "Tim");
l.put("6", "Brad");
System.out.println("LinkedHashMap elements...");
System.out.println("Key Value pair = "+l.entrySet());
}
}输出结果
LinkedHashMap elements... Key Value pair = [1=Jack, 2=Tom, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad]
