打印九九乘法表

如下代码：

 

public class PrintJJTable 
{
	public static void main(String[] args)
	{
		PrintJJTable t = new PrintJJTable();
		t.Display();
	}
	
	public void Display()
	{
		for(int i=1; i<=9; i++)
		{
			System.out.print("\t" + i);
		}
		
		System.out.print("\n    * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *");
		
		for(int i=1; i<=9; i++)
		{
			System.out.print("\n" + i + "   *\t");
			
			for(int j=1; j<=9; j++)
			{
				System.out.print(i*j + "\t");
			}
		}
	}
}

 

 

输出为：
