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...

Write a program and define the function "area" to find area of rectangle square and triangle.

16/03/2013 13:22
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...

To check whether the number is prime or composite

18/01/2013 08:24
  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"); } }  

To print squares of 10 numbers from one to ten

01/01/2002 08:24
  public class squaresofnumbers { public static void main(String args[]) { for(int i=1;i<=10;i++) System.out.println(i*i); } }  

Print whether the number is +ve or -ve

01/01/2002 08:22
  public class postivenegative { public static void main(String args[]) { int a=-90; if(a>0) System.out.println("the number is +ve"); if(a<0) System.out.println("the number is -ve"); else System.out.println("the number is 0"); } }
