I need to write an application that reads three intergers and prints their average, 2- write an application that reads two floating point numbers and prints their sum, difference, and product. I am doing programming projects in Java software solutions 5th edition for school.

Get user entered input data from keyboard. Use BufferedReader and InputStreamReader classes to receive the intput data.
Convert user entered String type value to appropriate type value .
compute data and display the result
what you need is this...
do second one first...
set 2 attributes: double x
double y
methods you should programme are: constructors
getX()
getY()
setX()
setY()
toString()
first one...
create a class with 3 attributes which are all doubles...
create the same as above except in the toString, instead of a list of calculations (pm me if you are unsure about this) seperated with the "\n" aswell as the + signs...just create the sum for average using the 3 inputs.
need any further help then pm me please, as I am beginning to wonder if this forum is a joke due to flamers as theres only one person offered to help me since I joined when I have answered quite some threads for my first day
you can add two integers in java simply by
class javaa
{
}
class javaa
{
double x;
double y;
double z;
javaa(int x,int y,int z)
{
this.x=x;
this.y=y;
this.z=z;
}
double setx()
{
this.x=x;
}
double getx()
{
return this.x;
}
double sety()
{
this.y=y;
}
double gety()
{
return y;
}
double setz()
{
this.z=z;
}
double getz()
{
return this.z;
}
double average()
{
double av;
av=(x+y+z)/3;
return av;
}
}
}
class driver
{
public static void main(String []args)
{
javaa j=new javaa(1,2,3);
j.av();
}
}
public static void main(String []args)
{
javaa j=new javaa(1,2,3);
j.av();
}
Actually you need to call the average() method because there is no method: [U]av[/U] declared in the class.
