Hi Friend,

Try the following codes:

1)
import java.text.*;
import java.lang.Math;
import java.util.*;
public class CompoundInterest
{
public static void main( String args[] )
{
Scanner input=new Scanner(System.in);
System.out.print("Enter Principal: ");
double principal=input.nextDouble();
System.out.print("Enter Rate OF Interest(%): ");
double r=input.nextDouble();
System.out.print("Enter Number OF Years: ");
double y=input.nextDouble();
double rate = r/100;
double amount;
DecimalFormat precisionTwo = new DecimalFormat( "0.00" );
StringBuilder sb=new StringBuilder();
for ( double year = 1; year <= y; year++ )
{
amount = principal * Math.pow( 1.0 + rate, year );
sb.append( year + "\t" +precisionTwo.format( amount ) + "\n" );
}

System.out.println(sb.toString());
}
}

2)
class Shape{
double pi=3.14;
Shape(int side){
System.out.println("Area and Perimeter of Square with side "+ side);

}
System.out.println("Area and Perimeter of Rectangle with length "+ length+" and breadth "+breadth);

}

System.out.println("Area and Perimater of Circle with radius "+ radius);

}
void area(int side){
System.out.println(side*side);
}

void area(long l,long b){
System.out.println(l*b);
}

void area(double r){
System.out.println(pi*r*r);
}

void perimeter(int side){
System.out.println(4 * side);
}
void perimeter(long l,long b){
double a=l+b;
System.out.println( 2 * a);
}
void perimeter(double r){
System.out.println(2 * pi * r);
}
}

public static void main(String[]ars){
Shape s1=new Shape(5);
s1.area(5);
s1.perimeter(5);

Shape s2=new Shape(4,5);
s2.area(4,5);
s2.perimeter(4,5);

Shape s3=new Shape(5.0);
s3.area(5.0);
s3.perimeter(5.0);
}
}

Thanks
