Thread: Homework help using max method

Okay I've got a homework assignment to write a program that reads integers, finds the TWO (2) largest of them, and counts their occurrences. I've managed to get the largest number but can I get any tips on how to find the second largest?
Here is my code so far and thanks in advance!

import java.util.Scanner;
 
public class Unit4PT1 {
	public static void main (String [] args){
	Scanner in = new Scanner(System.in);
	System.out.print("Enter numbers: ");
int max = -1;
int count = 0;
int number;
while((number = in.nextInt()) != 0){
if(number > max){
max = number;
count = 1;
} else if (number == max){
count++;
}
}
System.out.println("The largest number is " + max);
System.out.println("The occurence count of the largest number is " + count);
}
}

How would I compare the largest variable to the old largest? Here is what I now have

import java.util.Scanner;
 
public class Unit4PT1 {
	public static void main (String [] args){
	Scanner in = new Scanner(System.in);
	System.out.print("Enter numbers: ");
 
 
int max = -1;
int count = 0;
int largest;
int nextLargest;
while((number = in.nextInt()) != 0){
if(number > max){
max = largest;
count = 1;
} else if (number == max){
count++;
}
}
 
System.out.println("The largest number is " + max);
System.out.println("The occurence count of the largest number is " + count);
System.out.println("The second largest number is " + max);
System.out.println("The occurence count of the second largest number is " + count);
}
}

What I don't understand is how to assign a value to nextLargest. if(number > max) gives me largest but...

Haha I'm just getting more and more confused. Really wish I had a real life teacher. Here is what I now have but I don't think it makes sense.

import java.util.Scanner;
 
public class Unit4PT1 {
	public static void main (String [] args){
	Scanner in = new Scanner(System.in);
	System.out.print("Enter numbers: ");
 
 
int max = -1;
int count = 0;
int largest;
int nextLargest;
while((number = in.nextInt()) != 0){
if(number > max){
max = largest;
count = 1;
	} else if (number == max){
	count++;
	}else if (number > nextmax){
	nextmax = nextLargest;
	count = 1;
	}else if (number == nextmax){
	count++;
}
}
 
System.out.println("The largest number is " + max);
System.out.println("The occurence count of the largest number is " + count);
System.out.println("The second largest number is " + nextLargest);
System.out.println("The occurence count of the second largest number is " + count);
}
}

The new values would be:
max =6, count=1
nextMax = 5 count=2

So I've changed quite a bit over the past few days and I'm on the verge getting it right. I still have a few problems though. My output is 0 regardless of the integers I put in. I changed the while loop to an if and now my code is:

import java.util.Scanner;
public class idk {
 public static void main (String [] args)
 
{
 
        int max = 0;
        int maxcount = 0;
 
        int nextmax=0;
 
        int nextmaxcount=0;
 
        int number=0;
 
 
 
        Scanner input = new Scanner(System.in);
 
     System.out.print("Enter numbers: ");
 
    number = input.nextInt();
 
 
 
if(number != 0){
 
    if(number > max){
 
 
 
            maxcount = 1;
 
                    }
 
    else if (number == max){
 
        maxcount++;
 
                            }
 
    else if (number > max){
 
        number = nextmax;
 
        nextmaxcount = 1;
 
                            }
 
    else if (number == nextmax){
 
            nextmaxcount++;
 
                                }
 
                   }
 
    System.out.println("The largest number is " + max);
 
    System.out.println("The occurence count of the largest number is " + maxcount);
 
    System.out.println("The second largest number is " + nextmax);
 
    System.out.println("The occurence count of the second largest number is " + nextmaxcount);
 
    }
   }

Oops forgot a part, which I just edited in. And yes it compiles without errors.

The if loops should assign values to the four variables all of which print as 0. For some reason they do not.

Max and nextmax both have a value of 0. The variables should be assigned a value in

if(number != 0){
 
    if(number > max){
 
 
 
            maxcount = 1;
 
                    }
 
    else if (number == max){
 
        maxcount++;
 
                            }
 
    else if (number > max){
 
        number = nextmax;
 
        nextmaxcount = 1;
 
                            }
 
    else if (number == nextmax){
 
            nextmaxcount++;

So I tried to assign values and now it prints out that max is the first number I type and that the occurrence is one.

if(number != 0){
 
    if(number > max){
 
 	max = number;
 
            maxcount = 1;
 
                    }
 
    else if (number == max){
 
        maxcount++;
 
                            }
 
    else if (number > max){
	max = nextmax;
	number = max;
 
        nextmaxcount = 1;
 
                            }
 
    else if (number == nextmax){
 
            nextmaxcount++;
 
                                }
 
                   }

It is not working correctly. Say I enter the following numbers: 4 4 3 3 3 5 6 6 the program says:

The largest number is 4
The occurrence count of the largest number is 1
The second largest number is 0
The occurrence count of the second largest number is 1

It should say:

The largest number is 6
The occurrence count of the largest number is 2
The second largest number is 5
The occurrence count of the second largest number is 1
