A little confuse with String

[Kay Liew]

KB books stated in page 357.

x.replace('a','A');
System.out.println("x = " + x); //the output is still: x = Java

I got trouble in the //comment. I think the original 'Java" will turns into 'JAvA".

Isn't that so ?

Thanks,

Look at what the x.replace('a','A') statement is really doing. Is it assigning the value it gets from the replace function to the string x or is it just performing the action and throwing the value away?

ok ok .. i looked too far

I was thinking of x.replace('a','A'); as x=x.replace('a','A'); .
