To Demonstrate the Simple Recursion

Here is a Java Program to Demonstrate the Simple Recursion

class RecTest {
  int values[];

  RecTest(int i) {
    values = new int[i];
  }

  // display arrary -- recursively
  void printArray(int i) {
    if(i==0) return;
    else printArray(i-1);
    System.out.println("[" + (i-1) + "] " + values[i-1]);
  }
}

Here is a Main Class to Run above Class

class Recursion {
  public static void main(String args[]) {
    RecTest ob = new RecTest(10);
    int i;

    for(i=0; i<10; i++) ob.values[i] = i;
    
    ob.printArray(10);
  }
}
