int ki = inp.nextInt();

Scanner inpu = new Scanner(System.in);
System.out.println("kindly choose second number");
int kn = inpu.nextInt();

return ki;
return kn;

}

public static void main(String[] args) {

Raghav...
notice on your method declaration that you are declaring that you are returning a string but variable ki and kn are of type int

to fix this you can do the following:

return new String(ki);

or even this

Interger [the class btw] ki = new Interger(inp.nextInt());

return ki.toString();

note there may be errors in this code since i did it from pure memory, look into the specifics of how to do this on google

Continuing...

you can only return one object. you cannot do

return variable;
return variable2;

they both must be in the same array in order to return multiple values.

so i recomend to do this
public static String[] pin() {

String[] arr = new String[2];

//scanner and printout code here

int ki = inp.nextInt();
arr[0] = new String(ki);

int kh = inp.nextInt();
arr[1] = new String(kh);

return arr;
}

you will need to add the variable for the scanner and i did do this from memory so there may be some errors

i hope this helps
happy coding
