I believe that this example opens up stdin for the input. In other words, it isn't hung, it is waiting for you to type in your expression and press retrun isn't it? Check the main code to see where it is looking for the input to come from.

I did provide CLASSPATH to example folder which java has access to Expr.g, Test.java and performed "java Test" to execute, the execution doesn't happens it hangs simply.

I agree that I need to brush my basics on Java but in parallel can I have a way to execute. Could you throw some insights why while doing "java Test" when below two operation are successful -  

java org.antlr.Tool Expr.g
javac Test.java ExprLexer.java ExprParser.java

"java Test" hangs....

The java command will not automatically look in your home directory. Use the -cp option or include this directory in your CLASSPATH. You should take the Java tutorials online before going further I think.

Hello,

I did install antlr-3.2 on Linux x86_64 as below -
