What wrong in this compiler say error Intger.ParseInt not found

Question

import java.io.*;
public class CompountInterest
{
public static void main(String[] args) {
try{
DataInputStream x= new DataInputStream(System.in);
int p,r,t,n;

System.out.println("enter the principal amount:");
p=Intger.ParseInt(x.readLine());
System.out.println("enter the rate of interest:");
r=Intger.ParseInt(x.readLine());
System.out.println("enter the time period");
t=Intger.ParseInt(x.readLine());
System.out.println("enter the no of times that interest is compound perunit t");

n=Intger.ParseInt(x.readLine());

double amount=p*Math.pow(1+(r/n),n*t);
double cinterest=amount-p;
System.out.println("compound interest after"+t+"years:"+cinterest);
System.out.println("amount after"+t+"years:"+amount);
}
catch(Exception e)
{}
}
}

Answer 1

There is 'Integer' not 'Intger'

Also in Java method name starts from small letter so there would be 'parseInt()

method name should be camelCase in Java

Answer 2

But both are use for same thing
So why compile says problem

Answer 3

Thank I change that changes but compiler again say that
Playground/CompoundIntrest.java uses or overrides a deprecated API
And
Recompile with -Xlint: deprecation for detail
Then what do to solve it

Answer 4

Leena Patil

Yes because of DataInputStream which is deprecated now so you can use Scanner class to take inputs.

Scanner sc = new Scanner (System.in);

int a = sc.nextInt();

Answer 5

Ok

Answer 6

As I said deprecated means no longer use of DataInputStream

That's why compiler is giving error.
