Getting IOError Exception many times

#1

I am getting lot of IOErrror
Exception in thread “main” java.util.NoSuchElementException
NumberFormatException.
So far I tried Scanner Reader, BufferedReader but IOErrors everytime

#2

@sushant4573,
Can you share your code with me?

#3

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
for(int i = 1 ;i<n; i++)
{
if(i%2 != 0)
{
for(int j = 1;j<=i; j++)
{
System.out.print(1);
}
}
else
{
System.out.print(1);

			for(int j = 0;j<i-2;j++)
			System.out.print(0);
			
			System.out.print(1);
		}
		System.out.println();
	}
}

}

Got again IOError , Please help how to rectify it.
indent preformatted text by 4 spaces
import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
double a = sc.nextDouble();
double b = sc.nextDouble();
double c = sc.nextDouble();

	double root = Math.pow(b,2)-4*a*c;
	if(root<0) System.out.println("Imaginary");
	else
	{
		root = Math.sqrt(root);

		double val1 = -b-root/2*a;
		double val2 = -b+root/2*a;
		if(val1 == val2)
		{
			System.out.println("Real and Equal");
			System.out.println((int)val1+" "+(int)val1);
		}
		else{
			System.out.println("Real and Distinct");
			System.out.println((int)Math.min(val1,val2)+" "+(int)Math.max(val1,val2));
		}

	}
}
