You shouls also have a look at java naming convention..good habit when learning. login should start as uppercase — Snicolas

assuming the code is in a file named login.java...

compile with:

javac login.java

should produce login.class, run with:

java login

Oracle has a tutorial. Try this in a terminal:

  javac login.java
  java login

The Output window is typically also your console window. Try making your Output window visible.

For C++, there is an option in Netbeans for where Console should read from.
