Decompose a number in ones with problem in the deployment

I have made a program in java, which decomposes in a sum of numbers some, to a value x, which is entered by the user. The inconvenience that I have is when I deploy, since I always have an extra "+" sign, example: stable that the limit is 5.

1

1 + 1 +

1 + 1 + 1 +

1 + 1 + 1 + 1 +

1 + 1 + 1 + 1 + 1 +

and I get this answer. How could I do, to remove that extra sign so annoying? (I have tried in several ways, but I have not managed to reach the desired result)

code:

    String coma ="+";
    String serie="";
    int unos=1;
    int li=0;
    int cont=0;
    String u="1";
    Scanner sc = new Scanner(System.in);
    System.out.println("Ingrese limite para la generación de laa sucesión");
    li= sc.nextInt();
    int other;
    int other2;
    other=li;
    other2=li;
    other2=other2-1;
    int te=1;
    for(int i=1; i<=li; i++)
    {

        for(int j=0; j<(other-other2); j++)
        {
            if(i>1)
            {
                serie= u+coma;
                System.out.print(serie);

            }
            else
            {
                System.out.print(u);
            }

        }

        System.out.println("");
        other2--;



    }

Modifying the if with a composite condition to print serie to the limit minus 1.

if(i>1 && j<(other-other2)-1) {
  serie = u+coma;
  System.out.print(serie);
} else {
  System.out.print(u);
}

By the way, it is somewhat confusing about the variables other and other2

Before the form prints the ones you should print the first one, and within the for you print only the missing ones by first prefixing the plus sign (+) . example for 5

public static void main(String[] args) {
  int limite = 5;
  for(int i = 0; i < limite; i++){
    System.out.print("1");
    for(int avance = 0; avance < i; avance++){
      System.out.print("+1");
    }
    System.out.println();
  }
}

The output of this program is

1
1+1
1+1+1
1+1+1+1
1+1+1+1+1
