Question
What will s2 contain after following lines of Java code?
StringBuffer s1 = "Ram";
StringBuffer s2 = s1.append(" Ali");
Solution
The code you provided will not compile in Java because you are trying to assign a String to a StringBuffer. The correct way to declare and initialize a StringBuffer in Java is:
StringBuffer s1 = new StringBuffer("Ram");
After this correction, the code would look like this:
StringBuffer s1 = new StringBuffer("Ram");
StringBuffer s2 = s1.append(" Ali");
In this case, both s1 and s2 will contain "Ram Ali". This is because the append method in Java modifies the original StringBuffer (s1 in this case) and also returns the same StringBuffer reference. So, s2 is just another reference to the modified s1.
