Exercise 1:  Write a Java program (name it Practice_1_1) to print out on separate lines the following: your name, 
your birthday, your hobbies, your favorite book, and your favorite movie. Label each piece of information in the output. 
 
 
Exercise 2:  Write a Java program (name it Practice_1_2) to print out the following shape using stars:  
  
               *  
              * *  
             * * *  
            * * * *  
             * * *  
              * *  
               *  
 
Exercise 3:  Write a java program (name it Practice_1_3) to display the result of  
 
                      1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10  
 
Exercise 4:  Write a java program (name it Practice_1_4) to display the area and perimeter of a rectangle with 
width = 4 and height = 8. Use proper labels for the outputs. 
 
 
Exercise 5:  Study Chapter 1, section 10: Programming Errors, page 20.  
 
1. Type, compile, and run the program in Listing 1.4, page 20. Observe the syntax errors understand them. 
2. Type, compile, and run the program in Listing 1.5, page 21. Observe the run-time error and understand why it 
happened. 
3. Type, compile, and run the program in Listing 1.6, page 22. Observe the output and understand why the code 
gave the wrong output (due to logical error). 
 
 
Instructions: 
 
1.  Programs must be working correctly. 
2.  Programs must be completed and checked before working assignment #1. 
3.  Programs must be checked by the end of the designated lab session.
