I got inputMissMatch exception during my TCS exam

Question

public class Solution {

    public static void main(String args[])
        Scanner sc=new Scanner(System.in);
        for(int i=0;i<5;i++){
            int input1=sc.nextInt();
            sc.nextLine();
            String str1=sc.nextLine();
            Double input2=sc.nextDouble();
        }
    }

}

This is my code. I only got this exception in "int" and "double" input only in for loop. IF I write it out-side of for loop it working fine. Please any one can help me solve this problem, because I am getting this error in my TCS exam.

Unfortunately your question does no give me much information, however I will try to answer anyway (need that rep). Im assuming the issue you run into is a InputMismatchException ? This is probably something to do with you trying to pass a double (i.e. 12.0) into an int. Using something like System.out.println("Enter Int Input:") can help you highlight which input type you should be providing on the line. try/catch blocks can stop the error being thrown.

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);

    try {
        for (int i = 0; i < 5; i++) {

            System.out.println("i: " + i);
            System.out.println("Enter Int Value:");
            int input1 = sc.nextInt();
            sc.nextLine();
            System.out.println("Enter String Value:");
            String str1 = sc.nextLine();
            System.out.println("Enter Double Value:");
            Double input2 = sc.nextDouble();
        }
    } catch (InputMismatchException e) {
        System.out.println("Invalid input entered for variable type.");

    }
}
