Write a program to print febonicci series

public class febonicci
{
public static void main(String args[])
{
int c;
int a=0;
int b=1;
System.out.println(a+" "+b);
for(int i=3;i<=20;i++)
{
c=a+b;

public static void main(String args[])
{
int length=5;
System.out.println("area of rectangle is"+" "+area);
}
}

Write a program with function "convert" which takes the temperature in Celsius and converts the equivalent Fahrenheit value

20/03/2013 00:10

public class abc
{
static double a=1.8;
static double c=100;
static double b=32;
static void convert()
{
double farenheit=a*c+b;
System.out.println(farenheit);
}
public static void main(String args[])
{
convert();
}
}

Write a program with function "calculate" to except the time in minutes and convert in hours

20/03/2013 00:23

public class converter
{
static double minute=30;
static double b=60;
static void calculate()
{
double hour=minute/b;
System.out.println(hour);
}
public static void main(String args[])
{
calculate();
}
}

This type of calling function into main method is called as "call by reference" method

public class reference
{
int a=10;
int b=15;
void swap(reference ob1)
{
int c;
c=ob1.a;
ob1.a=ob1.b;
ob1.b=c;
System.out.println(a);
System.out.println(b);
}
public static void main(String args[])
{
reference ob1=new reference();
ob1.swap(ob1);
}
}

Same program can be made by using "Static" keyword

public class reference
{
static int a=10;
static b=15;
static void swap()
{
int c;
c=a;
a=b;
b=c;
System.out.println(a);
System.out.println(b);
}
public static void main(String args[])
{
swap();
}
}

This method of calling is also called as "call by values"

public class values
{
void swap(int a,int b)
{
int c;
c=a;
a=b;
b=c;
System.out.println(a);
System.out.println(b);
}
public static void main(String args[])
{
int x=10;
int y=15;
values ob1=new values();
ob1.swap(x,y);
}
}

This is also the simple method of calling functions in main method

public class xyz
{
void swap(int a,int b)
{
int c;
c=a;
a=b;
b=c;
System.out.println(a);
System.out.println(b);
}
void swap()
{
int a=5;
int b=6;
int c;
c=a;
a=b;
b=c;
System.out.println(a);
System.out.println(b);
}
public static void main(String args[])
{
xyz obj=new xyz();
obj.swap(8,9);
xyz obj1=new xyz();
obj.swap();
}}

Write a program with overloaded function volume() to calculate the volume of cube,cuboid and a cylinder

01/01/2002 08:01

public class husain
{
void volume(int l,int b,int h)
{
int volume=l*b*h;
System.out.println(volume);
}
void volume()
{
int side=5;
int volume=side*side*side;
System.out.println(volume);
}
void volume(double a,double b,double c)
{
double d=a*b*c;
double volume=d*b;
System.out.println(volume);
}
public static void main(String args[])
{
husain obj=new husain();
obj.volume(5,10,15);
husain ob1=new husain();
ob1.volume();
husain ob2=new husain();
ob2.volume(3.14,5,10);
}
}

Here is it

public class recsqutri
{
void area(int l,int b)
{
int area=l*b;
System.out.println(area);
}
void area()
{
int side=5;
int area=side*side;
System.out.println(area);
}
void area(double a,double b,double c)
{
double area=a*b*c;
System.out.println(area);
}
public static void main(String args[])
{
recsqutri obj=new recsqutri();
obj.area(5,6);
recsqutri obj1=new recsqutri();
obj1.area();
recsqutri obj2=new recsqutri();
obj2.area(0.5,2,1);
}
}
