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”);

Answer / prabhavith
replaceAll take two strings as parameter
but in the given question characters are given as parameter
hence it is an error

Answer / nikhil hegde
when u say s.replaceAll('j','k') their will be no output but
internally the string s will be stored as kava. so when u
ask for the output the output will be kava

If I will write String s=new String("XYZ"); String s1=new String("XYZ"); if(s.equals(s1)){ sop("True"); } else{ sop("False"); } This program will give me "True". But When I am creating my own class suppose class Employee{ public Employee(String name); } Employee e= new Employee("XYZ"); Employee e1 = neew Employee("XYZ"); if(e.equals(e1)){ sop("True"); } else{ sop("False"); } Then it will give the output as "False". Can I know what is happening internally?
