Hello Again
I like typing this.
This is fun.
Yay! Printing.
I’d much rather you ‘not’. I “said” do not touch this.

5. Write a java program that stores your Regd. No and year of admission into two variables, and displays their values on the screen.

My Regd. No is 171123142 and I have taken admission in B. Tech. In 2017.

6. Let we have two values 113, 2.71828. Then, declare two different variables to hold the given values. Write the java program to display the values of these two variables on the screen, one per line.

This is room # 113 e is close to 2.71828

7. Write a java program to exchange the values of two variables of integer type A and B using third temporary variable C.

8. Write a java program to exchange the values of two variables of integer type A and B without using third temporary variable.

9. What do each of the following print?
a.System.out.println(2 + “bc”);
b.System.out.println(2 + 3 + “bc”);
c.System.out.println((2+3) + “bc”);
d.System.out.println(“bc” + (2+3));
e.System.out.println(“bc” + 2 + 3);

10. What do each of the following print?
a. System.out.println(‘b’);
b. System.out.println(‘b’ + ‘c’);
c. System.out.println((char) (‘a’ + 4));

11. Suppose that a variable a is declared as int a = 2147483647
(or equivalently, Integer.MAX_VALUE ). What do each of the following print?

a. System.out.println(a);
b. System.out.println(a+1);
c. System.out.println(2-a);
d. System.out.println(-2-a);
e. System.out.println(2*a);
f. System.out.println(4*a);

12. Suppose that a variable a is declared as double a = 3.14159. What do each of the following print?

a. System.out.println(a);
b. System.out.println(a+1);
c. System.out.println(8/(int) a);
d. System.out.println(8/a);
e. System.out.println((int) (8/a));

13. Assume a string variable ruler1 contains “1” initially i.e.
String ruler1=”1”
Write a java program to print the following output using string concatenation. (You can take extra string variables)

1
1 2 1
1 2 1 3 1 2 1
1 2 1 3 1 2 1 4 1 2 1 3 1 2 1
