Usage

From source file:MainClass.java

public static void main(String[] arg) {
    char[] textArray = { 'T', 'o', ' ', 'b', 'e', ' ', 'o', 'r', ' ', 'n', 'o', 't', ' ', 't', 'o', ' ', 'b',
            'e' };

    String text = new String(textArray);

    System.out.println(text);//from  w ww  . j  a va 2 s .c o m
}

From source file:Main.java
