Creating a macro command to run a program

I have a file Main.javaand I want to run the program by passing test.txt to it

I know on the command line, I can write javac Main.java

After compilation, I can write java Main test.txtand this will execute the file launch and going throughtest.txt

If I just wanted to write main test.txtand run this launch of my file Main.classfor this, and if so, how?
