Java program to insert records using arraylist.
import java.util.*;
class employee
{
emp e1=new emp();
static int limit;
static Scanner s1=new Scanner(System.in);
ArrayList my_list=new ArrayList();
public static void main(String[] args)
{
System.out.println("WELCOME");
System.out.print("Enter the limit=");
limit=s1.nextInt();
employee em=new employee();
for(int i=0;i//this program does not print different records as entered according to the limit.it displays only the value last entered. example- if i enter 1st record- riti 1 2900
enter 2nd record-abc 2 1200
then it displays-
abc 2 1200
abc 2 1200
kindly help me.

Now, in output function, instead of :Rits rishii added your statment..but now it's displaying only 1 record & that too last one.
int j=1
inside the for loop, write
int j=0

simplycoder#-Link-Snipped-# : I would advise you to get your concepts cleared in this.
Knowing how arraylist works and why you have to create a new instance every time to add into it would be of a great help. -

1)WAP which will take input from user of n integers and print it.
2)WAP which will print the above list in ascending and descending order.
3)WAP which will take the input as a string arraylist.
"I love CE . I am proud to be a CEan ."
Print the count first.
Remove '.' character from the above sentence and print the list and the count.
4)Convert all the characters to lower case and upper case from the above question.
5)Reverse the sentence along but donot change the order of the alphabets in the word.
(exected output : . CEan a be to proud am I . CE love I).
6**)Calculate 100! using arrayList.
first five are pretty simple. Don't be demoralized if you don't get the 6th one
