Some Fun With Java & Mathematics

Hi Today i'm posting some JAVA Programs which are created to do some maths. I think you will enjoy this.






PRINTING PASCAL TRIANGLE

class A{
public static void main(String args[]){
int x=10;
A s=new A();
int d=s.q(x);
System.out.println("");
}

int q(int y){
int r=1;
int c;
int a;
int z;
for(a=y;a>=1;a--){
for(z=a;z>=1;z--)
System.out.print(" ");
for(c=1;c<=10-a;c++)
{
System.out.print("*");
System.out.print(" ");
}
System.out.println("*");
}
return r;
}
}



PRINTING SUMMATION OF NUMBERS


class A{
public static void main(String args[]){
int i;
for(i=1;i<=10;i++){
A w=new A();
int d=w.q(i);
System.out.println("Sum "+i+" = "+d);
}
}

int q(int a){
int i;
int x=0;
for(i=1;i<=a;i++){
x+=i;
}
return x;
}
}




PRINTING FACTORIAL OF NUMBERS


class C{

public static void main(String args[]){
int i;
for(i=1;i<=5;i++){
C c=new C();
int q=c.s(i);
System.out.println(i+"!="+q);
}
}

int s(int y){
int i;
int x=1;
for(i=1;i<=y;i++){
x*=i;
}
return x;
}
}
