7 points
In this post we can find couple of different ways how to convert char array to String in java.
Short solutions:
xxxxxxxxxx1
char[] charArr = {'a', 'b', 'c'};2
3
// solution 14
String str1 = new String(charArr); // abc5
6
// solution 27
String str2 = String.valueOf(charArr); // abc8
9
// solution 310
String str3 = String.copyValueOf(charArr); // abcxxxxxxxxxx1
public class Example1 {2
3
public static void main(String[] args) {4
5
char[] charArr = {'a', 'b', 'c'};6
7
String string = new String(charArr);8
System.out.println(string); // abc9
}10
}Output:
xxxxxxxxxx1
abcxxxxxxxxxx1
public class Example2 {2
3
public static void main(String[] args) {4
5
char[] charArr = {'a', 'b', 'c'};6
7
String string1 = String.valueOf(charArr);8
9
String string2 = String.copyValueOf(charArr);10
11
System.out.println(string1); // abc12
System.out.println(string2); // abc13
}14
}Output:
xxxxxxxxxx1
abc2
abcxxxxxxxxxx1
public class Example3 {2
3
public static void main(String[] args) {4
5
char[] charArr = {'a', 'b', 'c'};6
7
StringBuilder builder = new StringBuilder();8
for (char c : charArr) {9
builder.append(c);10
}11
12
String string = builder.toString();13
System.out.println(string); // abc14
}15
}Output:
xxxxxxxxxx1
abcxxxxxxxxxx1

Stream<Character> charStream = new String(charArr)11
.chars().mapToObj(c -> (char) c);12
13
String string = charStream.map(String::valueOf)14
.collect(Collectors.joining());15
16
System.out.println(string); // abc17

Character[] charArrBoxed = new String(charArr).chars()10
.mapToObj(c -> (char) c)11
.toArray(Character[]::new);12
13
String string = Joiner.on("").join(charArrBoxed);14
