Description

1. Install required softwares for java application development

2. Write a java class to print a text message in a console[ with and without eclipse ]

3. write a java method to add two numbers.

2. (Population projection) The U.S. Census Bureau projects population based on the

following assumptions:

Š One birth every 7 seconds

Š One death every 13 seconds

Š One new immigrant every 45 seconds

Write a program to display the population for each of the next five years. Assume

the current population is 312,032,486 and one year has 365 days. Hint: In Java, if

two integers perform division, the result is an integer. The fraction part is truncated.

For example, 5 / 4 is 1 (not 1.25) and 10 / 4 is 2 (not 2.5).

3. (Convert Celsius to Fahrenheit) Write a program that reads a Celsius degree in a

double value from the console, then converts it to Fahrenheit and displays the

result. The formula for the conversion is as follows:

fahrenheit = (9 / 5) * celsius + 32

Hint: In Java, 9 / 5 is 1, but 9.0 / 5 is 1.8.

Here is a sample run:

Enter a degree in Celsius: 43

43 Celsius is 109.4 Fahrenheit
