WAP to find area of circle​

i guess the correct option is letter a.

use contrasting font sizes, but the same font style

/* package whatever; // don't place package name! */

import java.util.*;

import java.lang.*;

import java.io.*;

class nestedloops {

public static void main (string [] args) {

int numrows = 4;

int numcols = 5;

int i,j;

char ch = 'a';

// note: you'll need to declare more variables

/* your solution goes here */

for ( i = 0; i < numrows; i++) { // outer loop runs for numrows times

for ( j = 0; j < numcols; j++) { // inner loop runs for numcols times

system.out.print(i+1);

system.out.print((char)(ch+j));

system.out.print(" ");

}

}

system.out.println("");

return;

}

}
