if you put an array of characters into a string will there be any errors

Question

Im just going to be upfront about this being for homework but I currently am not able to download java and check but will the code bellow cause any conversion errors?

char sentence[] = { 'H', 'o', 'w', ' ', 'a', 'r', 'e', ' ', 'y', 'o', 'u'};
String output = "The sentence is: ";

for(int i = 0; 1 < sentence.length; i++)
  output+= sentence[i]; 

System.out.println(output);

Answer 1

It would just be simpler to do this

char sentence[] = { 'H', 'o', 'w', ' ', 'a', 'r', 'e', ' ', 'y', 'o', 'u'};
System.out.println("The sentence is: " + String.copyValueOf(sentence));

Answer 2

The only problem your code has is in this line: for(int i = 0; 1 < sentence.length; i++) it should be: for(int i = 0; i < sentence.length; i++) other than that it will print your string follow by the "how are you"

Answer 3

I have just opened jshell.

jshell> String c = "cat"
c ==> "cat"

jshell> c += 's'
$3 ==> "cats"

In Java, if you concatenate an object, that object's toString method is called. If you concatenate a primitive, it is automatically converted to a String.

jshell> ArrayList<Integer> al = new ArrayList<>();
al ==> []

jshell> al.add(4);
$5 ==> true

jshell> al.add(5)
$6 ==> true

jshell> c += al
$7 ==> "cats[4, 5]"

Your code should compile as is.
