How do I apply the for-each loop to every character in a String?

Question

So I want to iterate for each character in a string.

So I thought:

for (char c : "xyz")

but I get a compiler error:

MyClass.java:20: foreach not applicable to expression type

How can I do this?

You need to convert the String object into an array of char using the toCharArray() method of the String class:

String str = "xyz";

char arr[] = str.toCharArray(); // convert the String object to array of char

// iterate over the array using the for-each loop.       

for(char c: arr){

    System.out.println(c);

}
