Here's a step-by-step guide to running a Java program in Linux terminal:
Step 1: Create a Java File
Create a .java
file in a folder and write your Java program inside it.
Step 2: Open Terminal and Navigate
Open the terminal, go to the specific file location using cd
command.
Step 3: Compile the Java File
Compile the .java
file using javac
command:
javac Filename.java
This will generate a .class
file, which is in binary format.
Step 4: Run the Java Program
Run the Java program using java
command:
java Filename
This will execute the program and display the output.
Key differences between .java
and .class
files:
-
.java
files contain human-readable Java code. -
.class
files contain binary code that can be executed by the JVM.
That's it! You've successfully run a Java program in Linux terminal.
