Runnable jar asking for user input on console on double click
To create a runnable JAR file that asks for user input on the console when double-clicked, you can use the following steps:
Create a Java application: Develop a Java application that prompts the user for input on the console. You can use the
Scanner
class or any other input method to read user input.javaimport java.util.Scanner;
public class UserInputApplication {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter your input: ");
String userInput = scanner.nextLine();
System.out.println("User input: " + userInput);
}
}
Compile and package the application: Compile the Java source code and package it into a JAR file. You can use the command-line Java compiler (
javac
) and the JAR tool (jar
) or build tools like Maven or Gradle.arduinojavac UserInputApplication.java
jar cfe UserInputApp.jar UserInputApplication.class
Create a batch script: Create a batch script (
.bat
file) that executes the JAR file using thejava
command. The batch script ensures that the console window remains open after the Java application completes.bash@echo off
java -jar UserInputApp.jar
pause
Save the batch script in the same directory as the JAR file.
Package the JAR and batch script: Place the JAR file and the batch script in a single directory.
Double-click to run: Double-click the batch script (
*.bat
) file to run the JAR file. It will open a console window and prompt the user for input. After the user enters the input, the program will display the entered value.
The batch script ensures that the console window remains open after executing the JAR file, allowing the user to see the output and enter input. The pause
command in the batch script prevents the console window from closing immediately.
By following these steps, you can create a runnable JAR file that asks for user input on the console when double-clicked.
