编写99乘法表的两种方案

public static void main(String[] args){
for(int i=1;i<10;i++){
for(int j=1;j<=i;j++){
int a=i*j;
System.out.print(j+"*"+i+"="+a+" ");
}
System.out.println();
}
}

public static void main(String[] args){

chengFaBiao(9);
}
public  static void chengFaBiao(int i){
if(i==1){
System.out.println(i+"*"+i+"="+i*i);

}else{
chengFaBiao(i-1);
for(int j=1;j<=i;j++){
System.out.print(j+"*"+i+"="+j*i+" ");
}
System.out.println();

}

}
