//Java Program displaying a simple numeric pattern
Pattern2.java
Any kind of patterns can be made in a programming language using for loops.
Here in this program the outer for loop determines the no of rows that we want for the pattern and the inner loop represents the no of columns per row.
Like the previous example here we replace the “*” by j(the variable value gets displayed)
So we get a numeric pattern
1
12
123
1234
12345
public class Pattern2
{
public static void main(String args[]){
for(int i=1; i<=5; i++){
for(int j=1; j<=i; j++){
System.out.print(j);
}//inner for
System.out.println();
}//outer for
}
}
