Program:-

public class BrainlyAnswer

{

public static void main(String args[ ])

{

int i,j;

for(i=1;i<=7;i++)

{

for(j=1;j<=i;j++)

{

System.out.print(j + " ");

}

System.out.println();

}

}

}

• See the attachment for programs and output
• The logic is very simple first the outer loop runs if the condition is true 1<=7
• The body enters the inner loop for printing
• Now it prints j until i if i is 1 it prints 1 if i is 2 it prints 1 2 and so on so i<=limit so if you want a particular limit just change the condition with the limit.
