I am writing a program that takes a group of numbers input from the keyboard and outputting them with tags to show which is largest and which is smallest. I have an idea of how this is supposed to work. Could any one give me help on how to make a for loop work with this?
I cannot get mine to work at all. I keep getting this really weird number every time I try to run the program. Thanks!!
int max;
int min;
int input;
int input2;
int input3;
max = Integer.MIN_VALUE;
min = Integer.MAX_VALUE;
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter 3 numbers.");
input = keyboard.nextInt();
input2 = keyboard.nextInt();
input3 = keyboard.nextInt();
if (input < min)
input = min;
else if (input2 < min)
input2 = min;
else if (input3 < min)
input3 = min;
else
min = 0;
if (input > max)
input = max;
else if (input2 > max)
input2 = max;
else if (input3 > max)
input3 = max;
else
max = 0;
System.out.println("The current min number is: " + min);
System.out.println("The current max number is: " + max);
This is what I had. It doesn't work. I don't understand how for loops are supposed to work. I read about them but I still don't understand them.
int max;
int min;
int input;
int input2;
int input3;
max = Integer.MIN_VALUE;
min = Integer.MAX_VALUE;
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter 3 numbers.");
input = keyboard.nextInt();
input2 = keyboard.nextInt();
input3 = keyboard.nextInt();
if (input < min)
input = min;
else if (input2 < min)
input2 = min;
else if (input3 < min)
input3 = min;
else
min = 0;
if (input > max)
input = max;
else if (input2 > max)
input2 = max;
else if (input3 > max)
input3 = max;
else
max = 0;
System.out.println("The current min number is: " + min);
System.out.println("The current max number is: " + max);
There should be sequence ofif statements like this
if (input < min){
min = input;
}
if (input2 < min){
min = input2;
}
if (input3 < min){
min = input3;
}
instead of
if (input < min)
input = min;
else if (input2 < min)
input2 = min;
else if (input3 < min)
input3 = min;
else
min = 0;

The wrong was that min variable was not assigned.

Is it appropriate implementation of for-statement?
int NumCount = 3;
for( int i = 0; i < NumCount; i++ ){
int input = keyboard.nextInt();
if (input < min){
min = input;
}
}

Those are the initial values: Integer.MAX_VALUE and Integer.MIN_VALUE

Read raindrop's last reply, there's an example how to use the for-statement and how to check an input number.
