problem about constructing Integer objects

[kevinn lee]

 
class B {

	Integer i = new Integer(10);
	Integer k=new Integer("12");
	Double l=new Double("45");
}   

Why doesent the code work for Integer but works for Double?

The code, as you wrote it compiles fine.

I didn't get your problem, sorry.

   C:\java\wow.java:12: cannot find symbol
symbol  : constructor Integer(int)
location: class Integer
    Integer i = new Integer(10);
                ^
C:\java\wow.java:13: cannot find symbol
symbol  : constructor Integer(java.lang.String)
location: class Integer
    Integer k=new Integer("12");
              ^
2 errors 

but this is what I get

You most likely created your own class named "Integer", at some point, and the Integer.class file is still laying around on your class path somewhere. If you can't find it on your own, use your operating system's "Find File" tool -- it's there somewhere!

Nice.

don't tell me you downloaded a jdk without the java.lang package or you are in trobule

Joking aside,

Check your path.

Open a shell and type javac - version
What do you see?

no the thing was that I had created a class named Integer and the compiler was looking for the constructor in that instead of the java.lang.Integer
thanks for replying
