Answer / cleon

@Pankaj:
What are you trying to do?, trying to call a function from
primitive type/reference, that that will never work. You can
call function on Object types.

Double d = 5.5D; //D is optional as by default it is treated
to be double value
String s = d.toString();

If one tries to do something like
String s = 5.5;
A type mismatch errors will be shown during compilation itself!!

Answer / pankaj

hi,
toString() method will also not work here.

double d=10.5;
String str= d.toString();

E:\Programs>javac conversionTest.java
conversionTest.java:6: double cannot be dereferenced
String str= d.toString();
^
1 error

The only way I found is as below and is working fine.

double d=10.5;
String str= ""+d+"";
System.out.println(str);

Answer / vinay kumar

Actually java doesn't have string type
there is only 'char' type.
Here String is a class (in java) ,
but i am saying one thing,
these comes 1 & if not 2 & if not 3

1) if in a line have float value that total conversion value
comes a float value.
other wise
2) if in a line have double value that total conversion
value comes a double value.
otherwise
3) if in a line have long value that total conversion value
comes a long value.
