allow me to spoon-feed you
char[] chars = {'s', 't', 'r', 'i', 'n', 'g', 's' };
String string = new String(chars);
When you have more than one char, you probably have them in an array. In that case you can use the String(char[]) constructor.char[] hello = new char[5];
hello[0] = 'h';
hello[1] = 'e';
hello[2] = 'l';
hello[3] = 'l';
hello[4] = 'o';
String salute = new String(hello);
