Incompatible type...

why is my code wrong?I changed the strings to int in order to be able to compare them...

Equality.java 
// I have imported a java.io.Console for you, it is named console. 
String firstExample = "hello";
String secondExample = "hello";
String thirdExample = "HELLO";
int fstExample = Integer.parseInt(firstExample);
int scdExample = Integer.parseInt(secondExample);
if(fstExample = scdExample) {
  console.printf("first is equal to second");
  System.exit(0);
}

There are several problems in your code First of all you don't have to convert the Strings to Integers. The task only ask you to write an if statement and check if the first string is equal second using .equals() method. So the code should look like this:

String firstExample = "hello";
String secondExample = "hello";
String thirdExample = "HELLO";

if(firstExample.equals(secondExample)){
  console.printf("first is equal to second");
}

EDIT: Why did you use the System.exit(0); method. This method is used just in special cases when you want to brute exit the program when a problem occurred.
