Java 程序打印任意数字的乘法表
给定一个数字 N 作为输入，我们需要打印它的表，其中 N>0。
例
Input 1 :- N = 7
Output :-
7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35
7 * 6 = 42
7 * 7 = 49
7 * 8 = 56
7 * 9 = 63
7 * 10 = 70
显示两种方式打印任意数字的乘法表:
- 用于循环打印 10 以内的乘法表。
- 使用 while 循环打印给定范围内的乘法表。
方法 1:生成乘法表，用于循环至 10
Java 语言(一种计算机语言，尤用于创建网站)
// Java Program to print the multiplication table of the
// number N.
class GFG {
public static void main(String[] args)
{
// number n for which we have to print the
// multiplication table.
int N = 7;
// looping from 1 to 10 to print the multiplication
// table of the number.
// using for loop
for (int i = 1; i <= 10; i++) {
// printing the N*i,ie ith multiple of N.
System.out.println(N + " * " + i + " = "
+ N * i);
}
}
}
Output
7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35
7 * 6 = 42
7 * 7 = 49
7 * 8 = 56
7 * 9 = 63
7 * 10 = 70
方法 2:-使用生成乘法表，同时循环到任意给定范围
Java 语言(一种计算机语言，尤用于创建网站)
// Java Program to print the multiplication table of
// number N using while loop
class GFG {
public static void main(String[] args)
{
// number n for which we have to print the
// multiplication table.
int N = 7;
int range = 18;
// looping from 1 to range to print the
// multiplication table of the number.
int i = 1;
// using while loop
while (i <= range) {
// printing the N*i,ie ith multiple of N.
System.out.println(N + " * " + i + " = "
+ N * i);
i++;
}
}
}
Output
7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35
7 * 6 = 42
7 * 7 = 49
7 * 8 = 56
7 * 9 = 63
7 * 10 = 70
7 * 11 = 77
7 * 12 = 84
7 * 13 = 91
7 * 14 = 98
7 * 15 = 105
7 * 16 = 112
7 * 17 = 119
7 * 18 = 126
