Here is your required code:

import java.util.*;
public class NumberExample{
    public static void main(String[]args){
        int sum=0,sumSquares=0;
        int num1=0,num2=0;
    Scanner input=new Scanner(System.in);
    System.out.print("Enter First Number: ");
     num1=input.nextInt();

    System.out.print("Enter Second Number: ");
     num2=input.nextInt();

    if(num1>num2){
    System.out.print("Your First Number is greater than second.So Please re-enter: ");
    num1=input.nextInt();
    }
    else{
        System.out.println("Odd Numbers: ");
while(num1 <= num2) {
if(num1%2 != 0) {
System.out.println(num1);
sumSquares+=(num1*num1);
}
if(num1%2 == 0) {
sum+=num1;
}
num1++;
}
System.out.println("Sum Of Even Numbers: "+sum);
System.out.println("Numbers and their squares between 1 and 10");
int i=1;
while(i <= 10) {
System.out.println(i+"    "+(i*i));
i++;
}
System.out.println("Sum Of square of odd Numbers: "+sumSquares);
}
    }
}
