Some of the content like 3 methods of calling functions into "MAIN" method and 9th STD. programs are uploaded
Write a program describing different methods of defining functions and calling them into main method
16/03/2013 20:09
Here are 4 methods of defining functions
public class functons
{
void add1()
{
int a=7;
int b=9;
int c=a+b;
System.out.println(c);
}
void add2(int a,int b)
{
int c=a+b;
System.out.println(c);
}
int add3()
{
int a=9;
int b=7;
int...
This program is used for swaping values ie interchanging one value with another eg: int a=9; int b=10; now interchange int a=10; int b=9; * also overloaded functions are explain ie having same name of function but different parameters used for it
16/03/2013 20:07
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...

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)
{

public class primecomposite
{
public static void main(String args[])
{
int n=56;
int c=0;
for(int a=1;a<=n;a++)
{
if(n%a==0)
c++;
}
if(c==2)
System.out.println("the number is prime");
else
System.out.println("the number is composite");
}
}
