Thread: Hi everyone i need some help

first of all i want to thanks to this great site and the people that willing to help.
So we start to learn the basics of objects and classes and i did a simple code.
the method get a string of a car model(from the main) and compare if it is a"ford" and the method need to print the 'new' value of firma ="ford".but it always return "null".what have i done wrong?;]

public class Car {
int price;
String firma;	
 
	public void getfirma(String firm){
 
 
		if(firm=="ford"){
		firma=firm;}
	System.out.println(firma);
	}
}

Don't use the comparison operator, '==', to determine the equality of String objects. Use the equals method, e.g.:

if ( thisString.equals( thatString ) )

Great thank you guys ,thanks you;]
