How to split the values from Multihaspmap ?

public static void main(String[] args) {
       MultiHashMap mp=new MultiHashMap();
       StringBuilder b = new StringBuilder();
       mp.put("a", 10);
       mp.put("a", 11);
       mp.put("a", 12);
       mp.put("b", 13);
       mp.put("c", 14);
       mp.put("e", 15);
       mp.put("b", 1);
       mp.put("b", 2);
       mp.put("b", 3);
       List list = null;

       Set set = mp.entrySet();
       Iterator i = set.iterator();
       while(i.hasNext()) {
       Map.Entry me = (Map.Entry)i.next();
       //list=(List)mp.get(me.getKey());
       System.out.println("key:"+me.getKey());
       System.out.println("value:"+me.getValue());
}
}

Above program output is :

key:e value:[15]
key:b value:[13, 1, 2, 3]
key:c value:[14]
key:a value:[10, 11, 12]

I want to print the values like
15
13 1 2 3
14
10 11 12

How to print the values as like above format ?

Try

System.out.println(me.getKey());
System.out.println(me.getValue().replaceAll("^\\[|\\]$", "").replaceAll(",", " "));

Great. Thanks for post.

public static void main(String[] args) {
       MultiHashMap mp=new MultiHashMap();
       StringBuilder b = new StringBuilder();
       mp.put("a", 10);
       mp.put("a", 11);
       mp.put("a", 12);
       mp.put("b", 13);
       mp.put("c", 14);
       mp.put("e", 15);
       mp.put("b", 1);
       mp.put("b", 2);
       mp.put("b", 3);
       List list = null;

       Set set = mp.entrySet();
       Iterator i = set.iterator();
       while(i.hasNext()) {
       Map.Entry me = (Map.Entry)i.next();
       list=(List)mp.get(me.getKey());

       for(int j=0;j<list.size();j++)
       {

       System.out.println(me.getKey()+": value :"+list.get(j));
       }
       }

       }

Above program output is :

e: value :15
b: value :13
b: value :1
b: value :2
b: value :3
c: value :14
a: value :10
a: value :11
a: value :12

I would like to get values :

e: value :15
b: value :13 1 2 3
b: value :13 1 2 3
b: value :13 1 2 3
b: value :13 1 2 3
c: value :14
a: value :10 11 12
a: value :10 11 12
a: value :10 11 12

How to get the values as like above ?
