Programming in Java Lab

To find the sum of any number of integers entered as command line arguments
To find the factorial of a given number
To learn use of single dimensional array by defining the array dynamically
To learn use of .lenth in case of a two dimensional array
To convert a decimal to binary number
To check if a number is prime or not, by taking the number as input from the keyboard
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
Write a program that show working of different functions of String and StringBufferclasss like setCharAt(, setLength(), append(), insert(), concat()and equals().
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
Modify the ―distance‖ class by creating constructor for assigning values (feet and inches) to the distance object. Create another object and assign second object as reference variable to another object reference variable. Further create a third object which is a clone of the first object.
Write a program to show that during function overloading, if no matching argument is found, then java will apply automatic type conversions(from lower to higher data type)
Write a program to show the difference between public and private access specifiers. The program should also show that primitive data types are passed by value and objects are passed by reference and to learn use of final keyword
Write a program to show the use of static functions and to pass variable length arguments in a function.
Write a program to demonstrate the concept of boxing and unboxing.
Create a multi-file program where in one file a string message is taken as input from the user and the function to display the message on the screen is given in another file(make use of Scanner package in this program)
