Closed Random Non-recurring

[Acrostic]

Mga sir, tinatry ko pong gumawa ng program using java. Ang aim ko po is to get a sample size, tapos magg' generate ng random numbers within the scope.

Sample:
Input Number: 10
Random Generated Number:
9
5
1
2
4
5
7
3
6
10

Salamat po sa makakapag bigay ng code, mas thank you kung ituturo kung paano nangyari para mas dama yung pag code haha

Edit:

Source Code: (Problem ko po is repeating yung numbers na inilalabas nyan)

Pwede naman po mag láρág ka ng code tapos pag may errors don ka lang help. Para d spoonfeeding hehe. Sure naman na pinagaralan nyo yan

Sir, na-edit ko na yung post, nakalagay na yung source code na meron ako hehe

Kahit anong number basta kung ilan ung iniput ganon din?

Mas preferred po na nasa range lang din po nung ininput, pero pwede na rin po kahit wala, basta hindi uulit yung numbers

                else
                    i--;
                }
            }
        }
    }

                }
            }
        }
    }

This is a good answer here. though stil has a room to improve.

What is happening here?

whatever the random() function generate, placed it on an 'arr' array type variable. each num generated will be evaluated from the isRecurred() custom function if its already been generated. If its not then display it. else, the variable i reverses from its previous position to regenerate random number.

Ayos na sir Arcturus salamat sa pagtulong
