class Principal {
    public static void main(String[] args) {
        Scanner entrada = new Scanner(System.in);
        ArrayList colecao = new ArrayList();
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 2; j++) {
                System.out.println("Insira um nome.");
                colecao.add(entrada.next());
            }
        } for (Object resolucao:colecao) {
            String formato = "| %-15s | %-10s |%n";
            System.out.format("+---------------+----------+%n");
            System.out.printf("| Nome          | Nome 2   |%n");
            System.out.format("+---------------+----------+%n");
            System.out.format(formato, resolucao, resolucao + "%n");
            System.out.format("+---------------+----------+%n");
        }
    }
}

I need to display separately using a for-each and that's where the problem is, how to display the right item in the right column?

This response was for an earlier version that the question already had.

The println should already break the lines, try the variant below, if it is a platform difference problem:

ArrayList exemplo = new Arraylist();
for (Object resolucao: exemplo) {
   System.out.println(resolucao);
}

Based on a comment you , you can split a string this way if your source is not an array:

Exemplo = original.split("\n");

for (Object resolucao: exemplo) {
   System.out.println(resolucao + "\r\n");
}

Regarding line breaks:

To know the line break of the platform in use, Java has

String newLine = System.getProperty("line.separator");

Or from Java 7,

String newLine = System.lineSeparator();
