对多个map进⾏遍历并取值如果你只想输出⾃⼰想要的值不把取出的值放在另⼀个List⾥⾯可以不⽤list.add(),可以直接输出打印⾃⼰想要的值.例⼀(不同类型的map遍历取值):
import java.util.*;
import Matcher;
import Pattern;
public class ceshi {
leaguepublic static void main(String[] args) {
List<String> list = new ArrayList<>();
Map<String, Integer> map1 = new HashMap<>();
map1.put("this is 1", 1);
Map<String, Character> map2 = new HashMap<>();
map2.put("this is a", 'a');
Set<Map.Entry<String, Integer>> entries = Set();
for (Map.Entry<String, Integer> entry:entries) {
Set<Map.Entry<String, Character>> entries1 = Set();
学习英语的网站for (Map.Entry<String, Character> entry1 :entries1){
list.Key()+"|"+Key());
list.Key()+"|"+ Value());
list.Value()+"|"+Key());
list.Value()+"|"+Key());//把取出的值放在⼀个集合⾥⾯,取的值可以根据⾃⼰的需要,要key取key,要value取value. }
}

Set<Map.Entry<String, HashMap<String, Integer>>> entries = Set();
for (Map.Entry<String, HashMap<String, Integer>> entry : entries) {
// System.out.Key());
Set<Map.Entry<String, Integer>> entries1 = Value().entrySet();
for (Map.Entry<String, Integer> stringIntegerEntry : entries1) {指挥官英文
list.Key()+"\t"+Key()+" "+Value());

}
for (int i = 0; i < list.size(); i++) {
String s = (i);
System.out.println(s);
}
}
