what is wrong with this code

Question about the task

Cat code won't compile

Java Syntax, Level 7, Lesson 12

Resolved

Please help me solve this

Task: The program reads data about cats from the keyboard and displays it on the screen.

For example:

Cat's name: Tiger, age: 6, weight: 5, tail: 22

Cat's name: Missy, age: 8, weight: 7, tail: 20

Requirements:

The program must read data from the keyboard.
If the user enters an empty string instead of a name, the program should display the data on the screen and terminate.
If the user enters: Tiger, 6, 5 and 22 (each value on a new line), then the program should display "Cat's name: Tiger, age: 6, weight: 5, tail: 22".
If the user enters: Missy, 8, 7 and 20 (each value on a new line), then the program should display "Cat's name: Missy, age: 8, weight: 7, tail: 20".
If the user enters: Tiger, 6, 5, 22, Missy, 8, 7 and 20 (each value on a new line), then the program should display two lines: "Cat's name: Tiger, age: 6, weight: 5, tail: 22" and "Cat's name: Missy, age: 8, weight: 7, tail: 20".
