I'm trying to write some code that makes the user input a valid username and they get three tries to do it. Every time I compile it I get an else without if error wherever I have a else if statement.
Scanner in = new Scanner(System.in);
String validName = "thomsondw";
System.out.print("Please enter a valid username: ");
String input1 = in.next();
if (input1.equals(validName))
{
System.out.println("Ok you made it through username check");
}
else
{
String input2 = in.next();
}
else if (input2.equals(validName))
{
System.out.println("Ok you made it through username check");
}
else
{
String input3 = in.next();
}
else if (input3.equals(validName))
{
System.out.println("Ok you made it through username check");
}
else
{
return;
}
You are misunderstanding the use of if-else
if(condition){
//condition is true here
}else{
//otherwise
}else if{
// error cause it could never be reach this condition
}

You can have
if(condition){
}else if (anotherCondition){
}else{
//otherwise means 'condition' is false and 'anotherCondition' is false too
