Can anyone help me figure out why my if statements are not executing properly? When the program executes with 7 as the value for num it should be executing the first line, but instead it goes to the third and displays, " a single digit."

public static String numberInfo(int num){
//TODO student
String numInfo;

if (num == 7) {
numInfo = "lucky sevens!";
}
if (num == 42) {
numInfo = "the answer to life the universe and everything.";
}
if (num < 10) {
numInfo = "a single digit.";
}
else {
numInfo = "a positive number.";
}
return numInfo;
}

Answer:

For the value of 7 of num, there are actually two if statements that are true and their contained code is executed.

So your line numInfo = "lucky sevens!"; is executed for sure, but then numInfo gets overwritten with by numInfo = "a single digit.";

To fix it, you have to decide how you want the program to behave, since technically, both numInfo's are equally correct.

- if you want to execute at most one if condition, chain them together like if (...) { ... } else if(...) { ... } etc.

- if you want to return multiple numInfo's, turn it into a collection where you add strings
