I'm creating a program whose idea was to get a text with a few words and break them in "," . Only you're reading only part of the text.

Follow the code and text below:

public static void main(String[] args) {
    String colunas = "";

    System.out.println("Cole o texto a ser quebrado por virgula :");
    Scanner entrada = new Scanner(System.in);
    while (entrada.hasNext()) {
        if(entrada.nextLine() == null || entrada.nextLine().equals(""))
        {
            break;
        }
        colunas += entrada.nextLine();

    }

    //colunas = entrada.nextLine();
    String[] split = colunas.trim().split(",");

    for (String c : split) {

        System.out.println("FIELD " + c + " AS CHAR");

    }
}

I think the problem is this condition within your loop, because invoking nextLine() within if , you are requesting data entry.

Switch:

while (entrada.hasNext()) {
    if(entrada.nextLine() == null || entrada.nextLine().equals(""))
    {
        break;
    }
    colunas += entrada.nextLine();

}

by:

while (entrada.hasNext()) {

    String str = entrada.nextLine();

    if(str  == null || str.equals(""))
    {
        break;
    }
    colunas += str;

}

I got it

public static void main(String[] args) {
    String colunas = " ";

    System.out.println("Cole o texto a ser quebrado por virgula :");
    Scanner entrada = new Scanner(System.in);

    while(entrada.hasNext()) {
        colunas += entrada.nextLine();
        if (colunas.contains(";")) {
            break;
        }
    }

    colunas = colunas.replace("     ","");
    String[] split = colunas.split(",");

    for (String c : split) {


        System.out.println("FIELD " + c + " AS CHAR");

    }
}
