Java 在hashmap中去掉逗号
我在Java中的Hashmap中有一个键值对，我以下面的方式遍历该映射Java 在hashmap中去掉逗号,java,android,Java,Android,我在Java中的Hashmap中有一个键值对，我以下面的方式遍历该映射 ArrayList<String> mysection = new ArrayList<String>(); ArrayList<String> temp = new ArrayList<String>(); Iterator it = Map.entrySet().iterator(); while (it.hasNext()){
ArrayList<String> mysection = new ArrayList<String>();
ArrayList<String> temp = new ArrayList<String>();
Iterator it = Map.entrySet().iterator();
while (it.hasNext()){
Map.Entry pairs = (Map.Entry)it.next();
System.out.println(" = " + pairs.getValue());
mysection.add(pairs.getKey().toString());
temp.add(pairs.getValue().toString());
it.remove(); // avoids a ConcurrentModificationException
