程序:
public class pattern{
public static void main(String []args){
int lines=8;
int i,j;
for(i=1;i<lines;i++){
// this loop is used to print the lines
for(j=1;j<=lines/2;j++){
// this loop is used to print numbers
if(i==j){
System.out.print(j);
}
else if(i>4 && j==lines-i){
System.out.print(j);
}
else{
System.out.print(" ");
}
}
j=j-2;
while(j>0){
//this loop is used to print numbers
if(i==j){
System.out.print(j);
}
else if(i>4 && j==lines-i){
System.out.print(j);
}
else{
System.out.print("");
}
j--;
}
System.out.println("");
}
}
}
