Question

I’m trying to build a program that goes like this:
User enters 3 numbers.
System prints out ascending sequence of numbers from the lowest value number to highest value number input by the user.
Eg: if user inputs 1 then 4 then 8 it should print out 1,2,3,5,6,7,8 omitting 4 as it is the number with middle value.
How do I get the program to omit this number?

System.out.print("Enter a number: ");
int n1 = Integer.parseInt(in.readLine());
System.out.print("Enter a number: ");
int n2 = Integer.parseInt(in.readLine());
System.out.print("Enter a number: ");
int n3 = Integer.parseInt(in.readLine());
int i = 0;
if ((n1 > n2) && (n2 > n3)) {
    for (i = n3; (i <= n1); i++) {
        String o = i + ",";
        System.out.print(o);
    }
}
else if ((n1 > n3) && (n3 > n2)) {
    for (i = n2; (i <= n1); i++) {
        String o = i + ",";
        System.out.print(o);
    }
}
else if ((n2 > n3) && (n3 > n1)) {
    for (i = n1; (i <= n2); i++) {
        String o = i + ",";
        System.out.print(o);
    }
}
else if ((n2 > n1) && (n1 > n3)) {
    for (i = n3; (i <= n2); i++) {
        String o = i + ",";
        System.out.print(o);
    }
}
else if ((n3 > n2) && (n2 > n1)) {
    for (i = n1; (i <= n3); i++) {
        String o = i + ",";
        System.out.print(o);
    }
}
else if ((n3 > n1) && (n1 > n2)) {
    for (i = n2; (i <= n3); i++) {
        String o = i + ",";
        System.out.print(o);
    }
}
System.out.println("\n" + "The sum of the sequence is " + i);

You are over complicating things greatly.

Have the user enter 3 numbers and read them in three variables a, b, and c. Then just use a for-loop to iterate from a to c, and if the value is equal to b then don’t print.

System.out.print("Enter a number: ");
int a = Integer.parseInt(in.readLine());
System.out.print("Enter a number: ");
int b = Integer.parseInt(in.readLine());
System.out.print("Enter a number: ");
int c = Integer.parseInt(in.readLine());

for(int i = a; i < c; i++)
{
   if(i != b)
      System.out.println(i);
}

Iteration makes your life easy.
