We will be doing this assignment in Class 2nd week: fill in questionnaire, log on to blackboard, take quiz 1 and also login to lab computers.

Install JDK-Java and Textpad at home, Help File.

First write a program that prints hello your full name then,

Write a program that reads in two integers n1 and n2 and outputs...

• Hello Your Full Name
• value of n1 + value of n2 = n1+n2
• value of n1 - value of n2 = n1 - n2
• value of n1 * value of n2 = n1 * n2

Nota Bene, these three all produce different output, but only one is the best choice...

1. System.out.println( "Sum n1+n2 = " + n1 + n2 );
2. System.out.println( "Sum " + n1 + " + " + n2 + " = " + (n1+n2) );
3. System.out.println( "Sum n1 + n2 " ); System.out.println( n1 + n2 );

Assignment Modifications

Read in a floating pointing number and then a string/character C,F or K

Translate the given temperature to the other two temperatures.

So Given 0 C Output 0 Celsius 32 Fahrenheit 212 Kelvin

Hints Lots of Ways to do this program, an easy way to do this is...

initialize C,F and K to same termperature none of them can reach

get C from K; get C from F;
Using C get F, then K

Chapter 3 4th edition Page 217 Project #4; Chapter 4 5th edition Page 231 Project #6;

Read exam grades 0..100; Display total number of A,B,C,D, and F; Negative input terminates data.

Chapter 4 4th Edition, Chapter 5 5th Edition- Defining Classes and Methods

it has one field number;

and these methods...

1. doubleValue returns the double value of the number
2. tripleValue returns triple value of the number
3. abs returns absolute value of the number
4. cubeValue returns the cube value of number
5. readInput to read in the number
6. writeOutput to write out the number, and all number info
