Discussion Forum : Operators and Assignments - Finding the output (Q.No. 3)
3.
What will be the output of the program?
class PassS
{
public static void main(String [] args)
{
PassS p = new PassS();
p.start();
}
void start()
{
String s1 = "slip";
String s2 = fix(s1);
System.out.println(s1 + " " + s2);
}
String fix(String s1)
{
s1 = s1 + "stream";
System.out.print(s1 + " ");
return "stream";
}
}
Answer: Option
Explanation:
When the fix() method is first entered, start()'s s1 and fix()'s s1 reference variables both refer to the same String object (with a value of "slip"). Fix()'s s1 is reassigned to a new object that is created when the concatenation occurs (this second String object has a value of "slipstream"). When the program returns to start(), another String object is created, referred to by s2 and with a value of "stream".

@Remya : Remember array is an Object in Java whereas Boolean is just a variable.

Here in this s1 in fix has value "slipstream" how come it changed to "slip" when control returned to start()? Can any one help me?

Is java support multiple inheritance?

It will not change the value of s1, it will create a new object of that string. So string immutable.

String is immutable then why s1 = s1 + "stream" is not giving any error.

What is the difference between system.out.print and system.out.println?

In the case of array, if fix method refers to same element, how it changes in the case of boolean?
