308 PointsWhat am i doing wrong?
I cant understand my mistake with help of preview mode please help. Here's what i had to do:"Declare another variable, naming this one the camel-cased version of "last name". Use console.readLine to store the user's last name into this new variable."
// I have imported java.io.Console for you. It is a variable called console.
String firstName = "Bla";
String firstName = console.readLine("Tom");
String lastName = "Tom";
String lastName = console.readLine("Tom");

28,694 Pointsyou can reassign a value to a variable, but you can't redefine a variable in the same scope.
// I have imported java.io.Console for you. It is a variable called console.
/*
//this is illegal code as it tries to define an already existing varaible
String firstName = "Bla";
String firstName = console.readLine("Enter a First Name:");
*/
/*
//this would work but is inefficient. It creates the variable, assigns it a value and then overwrites the value.
String firstName = "Bla";
firstName = console.readLine("Enter a First Name:");
*/
/*
//this eliminates the extra assignment.
String firstName; // variable is declared
firstName = console.readLine("Enter a First Name:"); //value is assigned
*/
String firstName = console.readLine("Enter a First Name:"); //declaration and assignment in a single step.
String lastName = "Tom";
lastName = console.readLine("Enter a Last Name:");
