Here is a basic example of how to create an array in Java and to then loop through the items in the array.
public class Main {
public static void main(String[] args) {
String[] fruit = {"apple", "banana", "grapes", "orange"};
for (String item : fruit) {
System.out.println(item);
}
}
}
Or, as a bit of a more practical example, let's say you have a Java app that will be exported as a runable JAR. In this example, args can be passed into the main method.
public class Main {
public static void main(String[] args) {
for (String server : args) {
System.out.println(server);
}
}
}
In Eclipse, you can export the project as a Runable JAR file and then place the JAR file on a Linux system, and use the java command to run the JAR file.
~]# java -classpath my.jar Main server1.example.com
server1.example.com
