遍历Java中Java LinkedHashMap的值
Java中使用迭代器来迭代LinkedHashMap的值。
让我们首先创建LinkedHashMap-
LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();
将一些元素添加到LinkedHashMap-
l.put("1", "Jack");
l.put("2", "Tom");
l.put("3", "Jimmy");
l.put("4", "Morgan");
l.put("5", "Tim");
l.put("6", "Brad");遍历值-
Collection res = l.values();
Iterator i = res.iterator();
while (i.hasNext()){
System.out.println(i.next());
}以下是迭代LinkedHashMap的值的示例-
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...");
Collection res = l.values();
Iterator i = res.iterator();
while (i.hasNext()) {
System.out.println(i.next());
}
}
}输出结果
LinkedHashMap elements... Jack Tom Jimmy Morgan Tim Brad
