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)
