One small correction in the video, when we concatenate x and y it will generate a new String in heap memory not in SCP. So in this example, "abcabc" will be stored inside the heap memory.

this is the internal implementation of concat() method in java:

Concat method:
public String concat(String str)
{
int otherLen = str.length();
if (otherLen == 0) {
return this;
}
int len = value.length;
char buf[] = Arrays.copyOf(value, len + otherLen);
str.getChars(buf, len);
return new String(buf, true);
}

Hi Naveen,


Can you please tell me solutions for the question in the below.


Split a String but don't split when character repeats.. input s="aHHHbYY";

Out put would be like output:[a, HHH, b, YY]


Thanks in advance.

Hi Naveen, could you please tell some tips to clear client round. It would be helpful

Very helpful video but just one correction, at 7:51 you mentioned Strings are the most commonly used data type. But it is not data type, it is class. We can call it data storage but not data type.

The value of x is abc Naveen in this question

Since abcabc is not refered by anyone, will it be removed by GC ?
