ممكن حل هذا السوال مافهمته...


Problem 1:

Write a program that asks the user to enter a favorite color, a favorite food, a favorite animal, and the first name of a friend or relative. The program should then print the following two lines, with the user’s input replacing the items in italics: I had a dream that Name ate a Color Animal and said it tasted like Food!

For example, if the user entered blue for the color, hamburger for the food, dog for the animal, and Jake for the person’s name, the output would be
I had a dream that Jake ate a blue dog and said it tasted like hamburger!
Don’t forget to put the exclamation mark at the end.

Notes:

This project requires careful attention to spaces in output messages. In particular, a space must be explicitly printed between the variables color and animal.

• File name
• Full deion of the coded program
• Author: Name of student
• Student ID
• Student email address
• Date submitted










/

File name: SillySentence.java
