As with any other object, you can create String objects by using the new keyword and a constructor. The String class has thirteen constructors that allow you to provide the initial value of the string using different sources, such as an array of characters:

char[] helloArray = { 'h', 'e', 'l', 'l', 'o', '.'};

String helloString = new String(helloArray);

System.out.println(helloString);

The last line of this code snippet displays hello.

Could u plz explain the two statements in bold above and what these two statements mean and why is it that System.out.println(helloString) would only display hello but not helloArray.

You have declared a character array named helloArray and initialize its values with characters h,e,l,l,o and .

The statement String helloString = new String(helloArray); store the elements of character array in the form of string. Now the array elements get connverted into string and System.out.println(helloString) prints the string hello.
