Java实现输出九九乘法表—for循环和递归算法

**Java实现输出99乘法表**

for循环

---

```java
public class ninenine {
 public static void main(String[] args){
 for (int i=1;i<10;i++) {
 for(int j=1;j<=i;j++) {
 System.out.printf("%d*%d=%d\t",j,i,j*i);
 }
 System.out.println("");
 }
 }
}
```

递归
----

```java
public class MultiTable {
 public static void main(String args[]) { 
 m(9); 
 } 
 
 /** 
 * 打印出九九乘法表 
 * https://blog.zeruns.tech
 */
 public static void m(int i) { 
 if (i == 1) { 
 System.out.println("1*1=1 "); 
 } else { 
 m(i - 1); 
 for (int j = 1; j <= i; j++) { 
 System.out.print(j + "*" + i + "=" + j * i + " "); 
 } 
 System.out.println(); 
 } 
 } 
}
```
