public class mult{
public static void main(String[] args) {

int[][] multtable = new int[11][11];

System.out.print("*");
for (int a=1;a<=size;a++)
{
System.out.print(" "+a) ;
}
System.out.println(" ");
for(int i=0; i<=10; i++)
{
// this loop is for rows
for(int j=0; j<=10; j++)
{
// this loop is for columns
multtable[i][j] = i*j;
}
}
System.out.print(" ");
System.out.print("------------------------------");
System.out.println("");

for(int i=1; i<11; i++)
{
System.out.print(i+"| ");

for(int j=1; j<11; j++)
{
// this ensures that all single-digit numbers will line up into columns
System.out.print(multtable[i][j]+" ");
}
// make a new line for every row
System.out.print(" ");
}
}
}

import java.util.Scanner;

public class Powers
{

public static void main(String[] args)
{

System.out.println("Welcome to the Squares and Cubes Table");
System.out.println();

Scanner sc = new Scanner(System.in);
String choice = "y";

while(choice.equalsIgnoreCase("y"))
{
// get the input from the user
System.out.println("Enter an Integer: ");
int integerNext = sc.nextInt();   

System.out.println("Number" + " " + "Squared" + " " + "Cubed");   
System.out.println("======" + " " + "======" + " " + "======");

for (int i = 1; i <= integerNext; i++) {
int numberSquared = (int) Math.pow(i, 2);
int numberCubed = (int) Math.pow(i, 3);

String message = " " + i + " " + numberSquared + " " + numberCubed;

System.out.print(message);
}

// see if the user wants to continue
System.out.print(" Continue? (y/n): ");
choice = sc.next();
System.out.println();
}
}
}
}
