What are vararg methods in Java?

In Java methods, parameters accept arguments with three dots. These are known as variable arguments.

sample(int args …){}

If they are used you can pass a different number of arguments each time you call these methods.

Example

public class Sample {    void demoMethod(String... args) {       for (String arg: args) {          System.out.println(arg);       }    }    public static void main(String args[] ) {       new Sample().demoMethod("ram", "rahim", "robert");       new Sample().demoMethod("krishna", "kasyap")    } }

Output

ram rahim robert krishna kasyap
