System.out.println("Enter your choice");

ch=in.nextInt();

switch(ch)

{

case 1:

int km,cm=0;

System.out.println("Enter the distance in km");

km=in.nextInt();

cm=km*100000;

System.out.println("The distance in centimetre="+cm);

break;

case 2:

int hr,min=0;

System.out.println("Enter the time in hours");

hr=in.nextInt();

min=hr*60;

System.out.println("The time in minutes="+min);

break;

case 3:

int c;

double f=0;

System.out.println("Enter the temperature in centigrate");

c=in.nextInt();

f=(9.0/5.0*c)+32;

System.out.println("The temperature in fahrenheit="+f);

break;

default:

System.out.println("Invalid Choice");

}

}

}

Output is attached.
