i seem to be having a problem with my code:
public static String Equilateral (int a, int b, int c){
if(a==b && b==c)
return "Equilateral";
}
It says "missing return statement" when i clearly have a return. Can anybody please help? Thank you very much.
It says that because if your conditional statement evaluates to false then there will be no return statement, your code would just skip over it.
Use this template instead:
if(a==b && b==c){
return "Equilateral";
}
else{
return "Not Equilateral!";
}
You should use some curly braces, it will help make sense of what you're doing and prevents errors like yours.
Alternatively, if you'd prefer having a single return statement:
String result = "Not Equilateral";
if(a==b && b==c){
result = "Equilateral";
}
return result;
Edit following OP's clarification:
If you set your code like this, then if your triangle is not equilateral, the returned String will be empty (nothing will be printed with System.out.print()).
String result = "";
if(a==b && b==c){
result = "Equilateral";
}
return result;
String variable in the method, assign it a value in the if or else blocks and return the variable instead of having multiple return statements.
Equilateral(), Isosceles() and Right() ? If that's so then you should make the method return a boolean instead of a String, Or just use a single method which returns the state of your triangle. Let me know which you're trying and I will make an edit to my answer.Imagine your if condition returned a false value for (a==b && b==c). What would you return in that case? Still Equilateral?
What you really need to have is
public static String Equilateral (int a, int b, int c){
if(a==b && b==c)
return "Equilateral";
return "";
}
or in a condensed format
public static String Equilateral (int a, int b, int c){
return (a==b && b==c)? "Equilateral" : "" ;
}
ifcondition
