How to obtain output?

Question

static void sayHelloTo(String name) {
System.out.println("Hello " + name);
}

This question is bascially an example in
Java chapter "Classes and Objects"
subchapter "Method Return Types"
in the topic "The Return Type" .
can someone please show the output and how to write the program.

Answer 1

your method requiares one parameter name which is of type String, but you call it without any parameters or arguments.
In generaly call is eg: someMethod( parameter1, parameter2, parameter3);
String are characters within quotes eg "some text" and you need one add in parameter place.

Answer 2

sayHelloTo("swali"); //how to call your method

Answer 3

Answer 4

if name is "swali", it outputs "Hello swali"

public class Program {
public static void main(String[] args) {
// here call your method sayHelloTo()
}
// here write your method sayHelloTo()
}

Answer 5

public class Program {

static void sayHelloTo(String name) {
System.out.println("Hello " + name);
}
public static void main(String[] args) {

sayHelloTo();
}

}

this is how I wrote my program above im getting error as displayed below:-

..\Playground\:9: error: method sayHelloTo in class Program cannot be applied to given types;
sayHelloTo();
^
required: String
found: no arguments
reason: actual and formal argument lists differ in length
1 error
