exception occured in java compiler

Question

I am a beginner in Java.I have JDK1.7.0 installed on windows 7 OS.I just wrote a sample java file where the file was not getting compiled and throws the below error.

Sam.java:5: ';' expected
                Sample p = New Sample();
                                            An exception has occurred in the compile
        r (1.7.0-ea). Please file a bug at the Java Developer Connection (http://java.su
        n.com/webapps/bugreport)  after checking the Bug Parade for duplicates. Include
        your program and the following diagnostic in your report.  Thank you.

Below is the code for Sam.java file

class sam
{
    public static void main(String args[])

    {
    Sample p = New Sample();

    p.show();
    p.display();


    }
}

I researched in google with the various compiler options but that did not help.I would like to understand the below errors. 1 - Sam.java:5: ';' expected 2 - An exception has occurred in the compiler (1.7.0-ea)

The class should be Sam not sam if the file is named Sam.java. Class names should begin with an upper case letter. Also the class should be public. Also, is there in fact another class called Sample? — Hovercraft Full Of Eels

Post the show() and display() methods. Errors seems to be in them, apart from the New keyword, which should have been new. — Rahul

@HovercraftFullOfEels: The class doesn't have to be declared public. — Makoto

It seems that you're using an early release version of the Java compiler. Have you tried updating to the most recent version? — Makoto

This is my Sample.java :class Sample { public void display() { System.out.println("Hello"); } public void show() { System.out.println("Good Day"); } } — Ak17

Sample p = New Sample();

Should be:

Sample p = new Sample();

Java is case sensitive.

E.G. This compiles cleanly here:

class Sam // class names should be EachWordUpperCase
{
    public static void main(String args[])
    {
    Sample p = new Sample();

    p.show();
    p.display();
    }
}

class Sample {
    public void show() {}
    public void display() {}
}

I think there's more to it, than just this new keyword problem. You better hang in around here to edit your answer with those as well(if the OP posts those 2 erroneous methods throwing the StringIndexOutOfBoundsException error)! :)

Andrew Thompson Over a year ago

@R.J (shrugs) Can't say I noticed the StringIndexOutOfBoundsException when I first commented, but the OP should not be attempting to run code that does not compile cleanly. My advice would be to fix the compiler errors first, then ask about other matters in other questions.

Rahul Over a year ago

I would expect the same, but unfortunately, the OP has no such plans. :( A few more mins, and I move on from this question, like FOREVER. :D

The new keyword has lower case characters :

Sample p = new Sample();

make Sample p = New Sample(); to Sample p = new Sample();

new is a reserved keyword which is used in java to create an object but as java is case sensitive new is different from New

There are also different ways of creating objects click to know more

all java key words are in lower case characters.
