Ex No1: Rational Numbers

AIM To write a Java Program to develop a class for Rationalnumbers.

ALGORITHM:

Step 1:-Declare a class called Rational and invoke a functioncalled gcda!b".

Step #:-$ind out t%e reminder w%en a is divided b& b and pass itas a parameter to t%e function.

Step ':-(reate an ob)ect for t%e class and declare t%e re*uiredstring and integer variables.

Step +:-(reate an ob)ect of class Data,nputStream .Read t%enumbers t%roug% t%e Readine" met%od into t%e ob)ect.

Step :-(onvert t%e input accepted into ,ntegers t%roug% t%eparse,nt met%od and store t%em in variables a and b.

Step /:-store t%e value returned b& t%e function 0(D in variablel.

Step :-Divide a b& l and b b& l and store t%em in variables 2and &.

Ex No:-6 Object Serialization

Aim:-To write a Java Program to randomly generate objects and write them into a fileusing concept of Object Serialization.

Algorithm-

Step !"eclare a class called #urrency .Open a file in output mode with a name.

Step $-%rite new data into the object using writeobject&' method.

Step (-Similarly create an input stream object .)ead it both in terms of "ollars and)upees.close the output object.

Step *-derive a class called "ollar which implements serializable interface.+nvo,e aconstructor and function to display the data.

Step Similarly declare a class called )upee with private variables and use print functionto display the variables.

Design anot%er t%read t%at generatesfibonacci numbers and writes t%em to anot%er pipe.T%e maint%read s%ould read bot% t%e pipes to identif& numberscommon to bot%.

ALGORITHM:
