Basic Scanner API

[guisome]

This simple program is printing "input 2" even if you type "yes". Why?
I know it's very basic, but I started reading some java tutorials about 2 days ago so I don't know much about it.

import java.util.Scanner;

class test {

public static void main(String[] args) {
System.out.println("Input something");
Scanner output = new Scanner(System.in);
String anw = output.nextLine();
if ( anw == "yes" )
System.out.println("input 1");
else
System.out.println("input 2");


}
}

Never compare Strings or any other object with == use the equals method instead.

Never say never. Ok there are some occassions when you do need to use == but when it comes to Strings and you want to compare contents then use the equals method.

Using the "equals" method the java points out :

test:java:9: incompatible types
found: java.lang.String
required: boolean
if ( anw = "yes" )

You didn't use the equals method. All you did is delete one = sign. That changes it from a comparison of equality to an assignment. Do you know what a method is and how to call it?

[guisome]

I didn't know what was that, but found a tutorial on a website, the program works.

if (anw.equals("yes"))

Thanks for answering the thread.
