how to replicate a string value.?

[shiniskumar]

consider the following code

String a="";
for(int i=1;i<4;i++){
a="--" ;
}

i want the value of a as follows
if i=1
a="-";
if i=2
a="--";
if i=3
a="---";
and so on.
i need the final value of 'a' . im appending the value of 'a' along with another string and putting it in a hashmap.
eg, hashmap h=new hashmap; h.put("name",a+"shini");
the result should be -shini in 1st case
,
--shini in 2nd case
---shini in 3rd case
how do i do this

Look up the API entry for string....if you can't do
String + char (which you may not be able to), there should be a method for "append" or "cat" (but I have a suspicion "this is " + "my String" will create 1 string "this is my String")

Just modify your for to

 for(int j=0;j<i;j++){
a= a + "-" ;
} 
 

After that you can then do
a = a + "shini";
and you are done.
