java编写九九乘法表

今天开始学习java，写了第一个程序，九九乘法表~~~~

public class ChengFa {

/**
* @param args
*/
public static void main(String[] args) {
System.out.println("九九乘法表");
System.out.print("    ");
for(int i=1; i<=9; i++)
{
System.out.print(i+"   ");
}
System.out.println();
for(int i=1; i<=9; i++)
{
System.out.print(i+"   ");
for(int j=1; j<=i; j++)
{
//if(j<=i)
System.out.print(i*j+"   ");
}
System.out.println();
}
// TODO Auto-generated method stub

}
