請問 用java語句輸出如圖片圖案應(yīng)該怎么做？

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

求java繪圖程序源代碼（加注釋），在如下圖的基礎(chǔ)上，在圖案種類上添加圓角矩形，求代碼

直線 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

怎樣編寫如下圖案的java代碼123456 12345 1234 123 12 1從上到下

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("");

}

}

}
