First step: Use Vim to write a Java program First.java is written in the JDK bin directory

 Public class first{      publicstaticvoid  main (String args[]) {        System.out.println ( "This is my first program." );      }    }

Step two:./javac/usr/java/jdk1.8.0_25/bin/first.java compile Build First.class

Step three: Run./java First output results

Note that if the source file is not written in the Java Bin directory, it is necessary to copy the First.class file to the bin directory to run, or the main class will be found without error.
