    Default Problem with day of month code

    I have an assignment where I'm supposed to write a program where the user inputs a month between 1-12 and then the right amount number in every month. I've tweaked the code a bunch of times, but I keep getting this error message:

    insert "}" to complete Statement KALENDER_3.java
    insert "}" to complete Block KALENDER_3.java

    The code:

    import java.util.*;
    import java.util.Scanner;

    public class KALENDER_3

    }

    public static void main(String[] args){
    Scanner scanner = new Scanner (System.in);
    System.out.print("Skriv ett månadsnummer: ");

    int månad = scanner.nextInt();
    if (månad < 1 || månad > 12) {
    System.out.print("Det finns ingen månad " + månad + ". Skriv igen");
    } else {
    System.out.print("Skriv vilken dag inom månaden: ");

    // JAG BÖRJAR MED MÅNADEN, JAG SKAPAR EN SCANNER SOM GÖR ATT JAG KAN LÄSA AV VARIABELN "MÅNAD"
    // SEDAN SKAPAR JAG ETT IF/ELSE FÖR HUR MÅNGA MÅNADER SOM MAN KAN SKRIVA MELLAN

    int dag = scanner.nextInt();

    //SEDAN SKAPAR JAG EN VARIABEL FÖR "DAG" KOMMANDOT,
    //EFTER DETTA BÖRJAR JAG GÖRA IF/ELSE FÖR VARJE MÅNAD SAMT ANTAL DAGAR

    if (månad == 1) {
    if (dag < 1 || dag > 31) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!"); }

    //FEBRUARI
    if (månad == 2) {
    if (dag < 1 || dag > 28) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");
    //MARS
    if (månad == 3) {
    if (dag < 1 || dag > 31) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");
    //APRIL
    if (månad == 4) {
    if (dag < 1 || dag > 30) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");


    //MAJ
    if (månad == 5) {
    if (dag < 1 || dag > 31) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");
    //JUNI
    if (månad == 6) {
    if (dag < 1 || dag > 30) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");
    //JULI
    if (månad == 7) {
    if (dag < 1 || dag > 31) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");
    //AUGUSTI
    if (månad == 8) {

    System.out.print("Rätt datum!");
    //OKTOBER
    if (månad == 10) {
    if (dag < 1 || dag > 31) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!");
    //NOVEMBER
    if (månad == 11) {
    } if (dag < 1 || dag > 30) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else {
    System.out.print("Rätt datum!"); }
    //DECEMBER
    if (månad == 12){
    }if (dag < 1 || dag > 31) {
    System.out.print("Månad " + månad + " har ingen dag " + dag + ".");
    } else{
    System.out.print("Rätt datum!");

    {



    I think I have just forgot to put in a few { } symbols, maybe an open loop? I can't figure it out. Can you see it?

    (The comments and quote strings are in swedish in case you are confused by them, I've also removed some of them for easier reading.)

    Well the last curly brace you have there is an opening. The last one should always be a closed braces. My advice would be to look through the code carefully and make sure that all if and else statements have matching curly braces. Put it in an IDE and auto indent/format it to make it easier to read.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
