Answer 1

I recommend you read about looping in Java, this is a base to start from.

        int num = 10;
    
    for(int i = 1; i < num; i++)
    {
        for(int j = 1; j <= i; j++)
        {
            System.out.print(j + " ");
        }
        System.out.print("\n");
    }

This should provide the triangular structure you are looking for. Definitely do take a look at the link above. Since you are new to Java, you should take a walk through this code before simply copying it. Really try to see how it works and more importantly, why it works.
