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

代码语言：javascript复制

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=%dt",j,i,j*i);
            }
            System.out.println("");
        }
    }
}

递归

代码语言：javascript复制

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(); 
    } 
  }  
}

java for循环 递归
