How to execute a Java method from inside shell scripts?
You can only call the main method. Design your main method such that it calls the method you want.
When I say call main method, you don't explicitly invoke it. It's the only entry point to a java program when you invoke it.
If your class looks like:
package com.foo;
public class Test {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
You can use the following command line to invoke the main from within the directory where you can find com/foo/Test.class (If you're in the classes directory in the structure shown far below):
java com.foo.Test
If you want to do so from a different (See the directory structure far below) directory, then you'll have to set classpath.
java -cp /path/to/classes com.foo.Test
Assume the below directory structure for clarity.
-path
-to
-classes
-com
-foo
>Test.class
