1、代碼如下：
public class Main
{
public static void main(String[] args) {
System.out.println("Hello World！");
//主循環(huán)
? for(int i =10;i0;i--){
? ? ? //輸出空格
? ? ? for(int k=i;k0;k--){System.out.print(" ");}
//輸出數(shù)字
? ? ? for(int j=i;j=10;j++){
? ? ? ? ? System.out.print(j+" ");? ? ? ? ? ? ?
? ? ? }System.out.println(" ");
? }
}
}
2、效果如圖
直線(xiàn) 是 Line2D
矩形是 Rectangle2D
弧 Arc2D
橢圓 Ellipse2D
圓角矩形是 RoundRectangle2D
上面的都在 java.awt.geom包里
public class TestArray {
public static void main(String[] args){
int array[] = {1,2,3,4,5,6};
for(int i = array.length-1;i = 0;i--)
{
for(int j =0;j=i;j++)
{
System.out.print(array[j]);
}
System.out.println("");
}
}
}
