why isn’t the loop starting again with different value of a other than 1.
package com.company;
import java.util.Scanner;
public class ForDemo {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println();
System.out.print("ENTER A NUMBER: ");
int b = sc.nextInt();
int a;
for(a=1 ;a<11;a=a+1)
for(b=b;b<16;b=b+1)
System.out.println(b + " * " + a + " = " + b*a);
}
}
output:
ENTER A NUMBER: 1
1 * 1 = 1
2 * 1 = 2
3 * 1 = 3
4 * 1 = 4
5 * 1 = 5
6 * 1 = 6
7 * 1 = 7
8 * 1 = 8
9 * 1 = 9
10 * 1 = 10
11 * 1 = 11
12 * 1 = 12
13 * 1 = 13
14 * 1 = 14 here it terminates!
required output:
1 * 1 = 1
2 * 1 = 2
3 * 1 = 3
4 * 1 = 4
5 * 1 = 5
6 * 1 = 6
7 * 1 = 7
8 * 1 = 8
9 * 1 = 9
10 * 1 = 10
11 * 1 = 11
12 * 1 = 12
13 * 1 = 13
14 * 1 = 14
15 * 1 = 15
1 * 2 = 2
2 * 2 = 4
3 * 2 = 6
4 * 2 = 8
5 * 2 = 10
6 * 2 = 12
7 * 2 = 14
8 * 2 = 16
9 * 2 = 18
10 * 2 = 20
11 * 2 = 22
12 * 2 = 24
13 * 2 = 26
14 * 2 = 28
15 * 2 = 30 and so on….
>Solution :
Simply assign your input variable (x) at the starting of the inner loop as below will solve your problem.
Till now you were initialized b as the last value of the previous iteration that is why your inner loop is not executed after the first iteration.
public class Simple {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println();
System.out.print("ENTER A NUMBER: ");
int x = sc.nextInt(); // take input as x
for(int a=1 ;a<11;a++) {
for (int b = x; b < 16; b = b + 1) { // initialize b with input variable(x)
System.out.println(b + " * " + a + " = " + b * a);
}
}
}
}
