java com.foo.Boo

Answer 4

All the answers only show the terminal commands to compile and run .java files but not the shell script to do so.

Below is the shell script. Let's call it compileRunJava.sh

javac $1
java ${1%.java}

You may need to giv terminal the permission to run your script -

$ sudo chmod 754 compileRunJava.sh

Let's say your .java file is Hello.java. To run the script, cd to the directory where you have Hello.java. Run the below command -

$ /path/to/shell/script/directory/compileRunJava.sh Hello.java
