Here is our character array.char[] ch = { 'T', 'E', 'S', 'T', 'I', 'N', 'G'};Create string object from some part of a string using the following String constructor. Through this we are fetching substring “IN” from the character array.String str = new String(ch, 4, 2);Example Live Demopublic class Demo { public static void main(String[] args) { char[] ch = { 'T', 'E', 'S', 'T', 'I', 'N', 'G'}; String str = new String(ch, 4, 2); System.out.println(str); } }OutputIN

Argument indices allow programmers to reorder the output. Let us see an example.Example Live Demopublic class Demo { public static void main(String[] args) { System.out.printf("Before reordering = %s %s %s %s %s %s", "one", "two", "three", "four", "five", "six" ); System.out.printf("After reordering = %6$s %5$s %4$s %3$s %2$s %1$s", "one", "two", "three", "four", "five", "six" ); System.out.printf("Before reordering = %d %d %d", 100, 200, 300); System.out.printf("After reordering = %2$d %3$d %1$d", 100, 200, 300); } }OutputBefore reordering = one two three four five six After reordering = ...
