How many String objects are created in the code

[Loveleen Saroya]

How many string objects are created in the following code:-

String s1 = "spring";
String s2 = s1+"summer";
s1.concat("fall");
s1.concat(s2);
s1+="winter";
System.out.println(s1+" "+s2);
 
  

1)2
2)4
3)8
4)9
im confuse that in System.out.println statement 2 objects r created or 1.
one more doubt.. if we put the code in the main method of a class will the object created be increase by 1 as the main method takes array of string as parameter.so the empty string.

class Test{
public static void main(String []arg){
String s1 = "spring";
String s2 = s1+"summer";
s1.concat("fall");
s1.concat(s2);
s1+="winter";
System.out.println(s1+" "+s2);
}}
 
  

thanks in advance

Hi Loveleen -

It appears you have posted this same question three times in two separate forums. We refer to this practice as 'cross-posting' and we discourage it on JavaRanch.

Please use one forum for a question. Do the best job you can to pick the proper one; if it can be better located a bartender or sheriff will assist.
