minT cannot be resolved

I was solving this problem:

Given two temperatures, return true if one is less than 0 and the other is greater than 100.

icyHot(120, -1) → true icyHot(-1, 120) → true icyHot(2, 120) → false

public boolean icyHot(int temp1, int temp2) { if (temp1 < temp2) { int minT = temp1; int maxT = temp2; } else { int minT = temp2; int maxT = temp1; }

return (minT < 0 && maxT > 100); }

I'm getting the error:

Error: return (minT < 0 && maxT > 100); ^^^^ minT cannot be resolved

Hey,

For code, wrap it in backticks. It's the button just below the escape button Do three ``` and then at the end use three more. Or there is a link at the bottom of this window, called "Markdown Cheatsheet". Click it the next time you are typing in a window and you will see it. It has all the info.

You had way to much code before. You are taking in two integers and checking to see if one is less than 0 and the other is greater than 100. Then return true of false. I think you over thought it.

The temperature values you don't need to think about. Those are passed in behind the scenes. So basically in order to be true, temp1 must be less than 0 AND temp2 must be greater than 100. So we can do it all on one line and return true or return false.

public boolean icyHot(int temp1, int temp2) { 
       if (temp1 < 0 && temp2 > 100) {  
               return true;
       } else { 
               return false;

See if that works for ya!
