How to convert an int array to String with toString method in Java
arrays, java, tostring
Solution
What you want is the `Arrays.toString(int[])` method:
import java.util.Arrays;
int[] array = new int[lnr.getLineNumber() + 1];
int i = 0;
..
System.out.println(Arrays.toString(array));
There is a static `Arrays.toString` helper method for every different primitive java type; the one for `int[]` says this:
public static String toString(int[] a)
Returns a string representation of the contents of the specified array. The string representation consists of a list of the array's elements, enclosed in square brackets (`"[]"`). Adjacent elements are separated by the characters `", "` (a comma followed by a space). Elements are converted to strings as by `String.valueOf(int)`. Returns `"null"` if `a` is null.
Problem
I am using trying to use the `toString(int[])` method, but I think I am doing it wrong: http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Arrays.html#toString(int[]) My code: ``` int[] array = new int[lnr.getLineNumber() + 1]; int i = 0; System.out.println(array.toString()); ``` The output is: ``` [I@23fc4bec ``` Also I tried printing like this, but: ``` System.out.println(new String().toString(array)); // **error on next line** The method toString() in the type String is not applicable for the arguments (int[]) ``` I took this code out of bigger and more complex code, but I can add it if needed. But this should give general information. I am looking for output, like in Oracle's documentation: The string representation consists of a list of the array's elements, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (a comma followed by a space).
