2. To find the factorial of a given number

3. To learn use of single dimensional array by defining the array dynamically.

4. To learn use of .lenth in case of a two dimensional array

5. To convert a decimal to binary number

6. To check if a number is prime or not, by taking the number as input from the keyboard

7. To find the sum of any number of integers interactively, i.e., entering every number from the keyboard, whereas the total number of integers is given as a command line argument

8. Write a program that show working of different functions of String and StringBufferclasss like setCharAt(, setLength(), append(), insert(), concat()and equals().

9. Write a program to create a ―distance‖ class with methods where distance is computed in terms of feet and inches, how to create objects of a class and to see the use of this pointer. CLICK HERE
