So, the project is asking me to take a string of whatever and feed it into an integer for the answer to life. I cannot get it to compile within TreeHouse. But, I downloaded Net Beans and got it to compile. It worked just fine. What am I doing wrong on the website?
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String answerToLife = "42";
Integer answer;
answer = Integer.parseInt(answerToLife);
System.out.print(answer);
}
}
Output
JAVA_HOME="C:\Program Files\Java\jdk1.8.0_301" cd G:\My Drive\Documents\NetBeansProjects\gradleproject1; .\gradlew.bat --configure-on-demand -x check run Configuration on demand is an incubating feature.
Task :compileJava UP-TO-DATE Task :processResources NO-SOURCE Task :classes UP-TO-DATE
Task :run 42 BUILD SUCCESSFUL in 741ms 2 actionable tasks: 1 executed, 1 up-to-date
But Tree House gives me an error.

44,806 PointsThe challenge is not expecting you to create a class. You only need to declare the variable answer
and set its value.
In your code, answer
is an Integer
rather than an int
. To make it an int
variable, you could change Integer answer;
to int answer;
.

Courses Plus Student 2,502 PointsTo create a variable with the integer data type, you use a lowercase int. If you use Integer, you are creating an Integer object, rather than a primitive variable.
public static void main(String[] args) {
String answerToLife = "42";
int answer;
answer = Integer.parseInt(answerToLife);
System.out.print(answer);
}
