Convert Character array to string in Java

Question

I have a Character array (not char array) and I want to convert it into a string by combining all the Characters in the array.

I have tried the following f

Answer 1

Actually, if you have Guava, you can use Chars.toArray() to produce char[] then simply send that result to String.valueOf().

Answer 2

First convert the Character[] to char[], and use String.valueOf(char[]) to get the String as below:

    char[] a1 = new char[a.length];
    for(int i=0; i<a.length; i++) {
        a1[i] = a[i].charValue();
    }
    String text = String.valueOf(a1);
    System.out.println(text);

Answer 3

int length = cArray.length;
String val="";
for (int i = 0; i < length; i++)
    val += cArray[i];
System.out.println("String:\t"+val);

Answer 4

Iterate and concatenate approach:

Character[] chars = {new Character('a'),new Character('b'),new Character('c')};

StringBuilder builder = new StringBuilder();

for (Character c : chars)
    builder.append(c);

System.out.println(builder.toString());

Output:

abc

Answer 5

Probably an overkill, but on Java 8 you could do this:

Character[] chars = {new Character('a'),new Character('b'),new Character('c')};

String value = Arrays.stream(chars)
                .map(Object::toString)
                .collect( Collectors.joining() );

Answer 6

It's probably slow, but for kicks here is an ugly one-liner that is different than the other approaches -

Arrays.toString(characterArray).replaceAll(", ", "").substring(1, characterArray.length + 1);
