how to count lower integers java

Question

Hi, this is my code that allows user to input number continously if the inputted value is lower than 5 and if number exceeds 5, it will print out "Program Terminated", However i want to edit this and count how many numbers that are lower than 5 were inputted. Can someone help me?

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner myInput=new Scanner(System.in);

int num, a;

for(a=0;a<=1;a++){
System.out.println("Enter a number:");

num=myInput.nextInt();

if(num > 5){
System.out.println("Program Terminated");
a+=1;
}
else{
a=0;

}
}
}
}

Answer 1

Your program accept only 2 numbers less than 5 because for loop runs only for a =0,1 next a=2, then a<=1 false then loop exits..
only 1 number greater than 5, because a++ makes to a=1, and in next in loop increment a++ cause a=2 so then loop stop.
you can enter any number of 5's.because input 5,last else part get executed, and set a=0, so a++ cause a=1 a<=1 is true, so this way if you put 5, it will reset a=0.

If you want any number of inputs, remove loop condition a<=1. Put a break condition for loop when
if(input>5)
break;
If input <=5, then increment a counter

.
.
int sum=0;
.

if(num<5)
++sum;
.
.
//now print sum.it will contains the sum of all nos inputted less than 5.

Answer 3

U have to initialise sum to 0.

That is, int sum=0;
Otherwise it gives error.

Answer 4

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner myInput=new Scanner(System.in);

int num, sum, a;

for(a=0;a<=1;a++){
System.out.println("Enter a number:");

num=myInput.nextInt();

if(num > 5){
System.out.println("Program Terminated");
a+=1;
}
else if( num < 5){
++sum;
System.out.println("Numbers inputted lower than 5:" + sum);
}
else{
a=0;

}
}
}
}

it says ++sum is not initialized

Answer 5

is my code wrong?

Answer 6

oh okay thank you!

Answer 7

so this is the updated code, it works but it only accept two lower integers, for example if i put 4 and 3 it doesnt accept any numbers anymore and the process is terminated. What maybe is the problem?

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner myInput=new Scanner(System.in);

int num, a, sum = 0;

for(a=0;a<=1;a++){
System.out.println("Enter a number:");

num=myInput.nextInt();

if( num < 5){
++sum;
System.out.println("Numbers inputted lower than 5:" + sum);
}
else if(num > 5){
System.out.println("Program Terminated");
a+=1;
}
else{
a=0;

}
}
}
}

it works now, thank you! ❤️
