程序:
public class pattern
{
public static void main(String[] args) {
int lines=4;
int i,j,k,l;
int space=0;
for(i=0;i<lines;i++){
// this loop is used to print lines
for(j=1;j<=space;j++){
// this loop is used to print space in a line
System.out.print(" ");
}
for(j=1;j<=lines;j++){
// this loop is used to print numbers in a line
if(j<=(lines-i))
System.out.print(j);
else
System.out.print("*");
}
j--;
while(j>0){
// this loop is used to print numbers in a line
if(j>lines-i)
System.out.print("*");
else
System.out.print(j);
j--;
}
if((lines-i)>9)
// this loop is used to increment space
space=space+1;
System.out.println("");
}
}
}
输出:
