// working of getChars() method
class Gfg1 {

System.out.println(destArray);
}
catch (Exception ex) {
System.out.println(ex);
}
}
}
Output:
GeeksforGeeks
// Java program to demonstrate
// exception condition in
// working of getChars() method
class Gfg2 {
public static void main(String args[])
{
String str = "Welcome! to GeeksforGeeks";
char[] destArray = new char[20];
try {
// Starting index 0 and ending index 24
str.getChars(12, 26, destArray, 0);
