Answer 2

public class Demo {
public static void main(String[] args) {
int i, j;
for (i = 1; i <= 5; i++) {
for (j = 1; j <= (5*2-1-(i * 2 - 1))/2; j++)
System.out.print(" ");
for (j = 1; j <= i; j++){
System.out.print(i);
System.out.print(" ");
}

for (j = 1; j <= (5*2-1-(i * 2 - 1))/2-1; j++)
System.out.print(" ");
System.out.println();
}
}
}
