Answer / vikneswarank

String s="java";
s.repalce('j','k');

System.out.println(s);

output is: java
because String is immutable.we cannt change of string
content.suppose u have to write
s=s.repalce('j','k');

output is :kava

Answer / puneet

No, the strings are immutable; the value of s will be the
same but new object kava will get crated which wil have no
refrence. s will refer to the same object which is not
changed.
s=s.replace("",""); should have worked...otherways

Answer / malli

Compile time error error.
String s=java here double quotes missing
and s.replaceAll('j','k'); here also we have to give double quotes.

Answer / prachi

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method replaceAll(String, String) in the type String is not applicable for the arguments (char, char)

will be thrown because in replaceAll(‘j’,’k’) : j & k are in single quote which defines as character not as string. For correct output first replace single quote with double quotes and second write s = s.replaceAll(“j”, “k”);
