How to Read Program Arguments in Java
In Java like in e.g. C the program options are part of the main method signature.
public static void main (String[] args)
We can write the hello world program like this:
public class Hello {
public static void main (String[] args) {
for (String s: args) {
System.out.println("Hello " + s);
}
}
}
Compile the program using javac Hello.java
and run the program.
java Hello one two "Claus Witt"
Resulting in the following output:
Hello one
Hello two
Hello Claus Witt
