I'm trying to create a multi-dimensional array in Java and I have it set up correctly however at the end it is saying '{' expected when there's already one there. This is the error line within the code
{
"Gerald 开发者_如何学编程Field", "U18", "Male", "Bourges", "14.01", "26.59","50.05"
};
Any suggestions on a way to fix this problem?
Edit:
Before this line is the rest of the array and this coding:
import javax.swing.JOptionPane;
public class CMS_Program
{
public CMS_Program()
{
String[][] names = new String[][]
{
{ Array here
All { are closed off too at the end.
Lot of context is still missing from your question. Anyway, the direct initialization of a String[][]
ought basically to be done as follows:
String[][] names = new String[][] {
{ "Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59", "50.05" },
{ "Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59", "50.05" },
{ "Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59", "50.05" },
{ "Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59", "50.05" },
{ "Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59", "50.05" }
};
However, you're better off using a List<Person>
where the Person
class look like this.
public class Person {
private String name;
private String id; // ??
private Gender gender;
private String city; // ???
private Double time; // Or so?
// ...
// Add/generate c'tor/getter/setter/equals/hashcode and other boilerplate.
}
This way you can just end up with
List<Person> persons = new ArrayList<Person>();
persons.add(new Person("Gerald Field", "U18", Gender.MALE, "Bourges", 14.01, 26.59, 50.05));
// ...
Just work with real objects/entities and don't fiddle low-level with complex arrays. Your code will become more self-documented and better maintainable.
Try this:
String[][] twoDimensional = {{"00", "01"}, {"10", "11"}};
It looks like you are doing this:
String[][] names = new String[][]
{
{
"Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59","50.05"
};
Note that there is a missing closing '}' If the closing brace is not missing then the semicolon needs to be after the second closing brace and not the first.
This should work out fine.
String[][] names = new String[][]
{
{"ramalam", "wam wam"},
{"ramalam", "wam wam"}
};
Could it be that you had a semi-colon after the array?
This is valid:
String[][] names = new String[][]
{
{
"Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59","50.05"
}
};
I can't see how this differs from your source though...
{
and }
are the beginning and end symbols of an array, and ,
is used to delimit the elements in the array..
If you create a multidimensional array (basically an array of array you need to use {..} for the array that is declared, as well as for any element within, because those are arrays too.
So, use something like this:
String[][] myMultiDimensionalArray = new String[][]
{
{
"Gerald Field", "U18", "Male", "Bourges", "14.01", "26.59","50.05"
},
{
"Name Lastname", "U18", "Male", "Bourges", "14.01", "26.59","50.05"
}
}
What the error is trying to say is that it sees only one dimension, and it was let to believe that there will be two.
