一个十分好的java基础学习的课件

public class GrapDemo
{
    public static void main(String args[ ])
    {
        char grap[ ][ ]=new char[10][ ];
        for (int i=0;i<=9;i++)
            grap[i]=new char[i+10];

        for (int i=0;i<=9;i++)
        {
            for (int j=0;j<9-i;j++)
                grap[i][j]=' ';
            for (int k=9-i;k<grap[i].length;k++)
                grap[i][k]=(char)(i+48);
        }

        for (int i=0;i<10;i++)
        {
            for (int j=0;j<i+10;j++)
                System.out.print(grap[i][j]);
            System.out.println( );
