Write a java program to find name of the class and its super class name by passing the class name at runtime?
class Ref1 {
public static void main(String[] args) {
if (args.length == 0) {
System.out.println("PLEASE PASS THE CLASS NAME..!");
} else {
try {
Class c = Class.forName(args[0]);
printSuperclass(c);
} catch (ClassNotFoundException cnfe) {
System.out.println(args[0] + " DOES NOT EXISTS...");
}
} // else
} // main
static void printSuperclass(Class c) {
String s = c.getName();
Class sc = c.getSuperclass();
String sn = sc.getName();
System.out.println(sn + " IS THE SUPER CLASS OF " + s);
} // printSuperclass
} // ref1
Output:
java ref1 java.awt.TextField
java.awt.TextComponent IS THE SUPER CLASS OF java.awt.TextField
public static void main(String[] args) {
if (args.length == 0) {
System.out.println("PLEASE PASS THE CLASS NAME..!");
} else {
try {
Class c = Class.forName(args[0]);
printSuperclass(c);
} catch (ClassNotFoundException cnfe) {
System.out.println(args[0] + " DOES NOT EXISTS...");
}
} // else
} // main
static void printSuperclass(Class c) {
String s = c.getName();
Class sc = c.getSuperclass();
String sn = sc.getName();
System.out.println(sn + " IS THE SUPER CLASS OF " + s);
} // printSuperclass
} // ref1
Output:
java ref1 java.awt.TextField
java.awt.TextComponent IS THE SUPER CLASS OF java.awt.TextField
