我想得到这个结果,其中_个空格字符:
*___*
_*_*_
__*__
public static void main(String args[]) {
int level = 2; // quantity line
int stars = 5; //quantity drawing stars
for(int i = 1;i <= level ; i++){
for(int j =1 ;j <= i; j++){
System.out.print(" ");
}
System.out.println("*");
}
}
到目前为止,我已经画好了
*__
_*_
__*
我不知道该如何绘画?

int rows=3; // quantity line
int cols=5; //quantity drawing stars
for(int i=0;i<rows;i++)
{
for(int j=0;j<cols;j++)
{
int k=cols-i-1;
if(i==j || j==k)
System.out.print("*");
else System.out.print(" ");
}
System.out.println();
}

int size=10; // Only one parameter is required which is quantity drawing stars
int length= size%2==0?size/2:size/2+1; // in case of odd one more line need to be print at last on which one Asteric appears.
for (int i = 0; i < length; i++) {
for (int j = 0; j < size; j++) {
if (i == j || i + j == size - 1) { //condition for diagonals
System.out.print("*");
} else {
System.out.print(" ");
}
}
System.out.println();
}
输出:
当大小= 10时;

您可以尝试以下代码,然后输出所需的内容。
for(int i=3;i>=1;i--)
{
for(int j=i;j<3;j++)
{
System.out.print(" ");
}
for(int j=1;j<=(2*i-1);j++)
{
if(j==1 || j==(2*i-1))
System.out.print("*");
else
System.out.print(" ");
}
System.out.println("");
}
