My problem is that only the 5th input gets printed while the rest is not

Scanner ns = new Scanner(System.in);

int n = 0;

int i=1;  
while(i<=5)
{  
    System.out.println("enter a number");  
    n = ns.nextInt();
    i++;  
}  

System.out.println(+n);
System.out.println(+n);
System.out.println(+n);
System.out.println(+n);
System.out.println(+n);

Let's say I typed 1, 2, 3, 4, 5 respectively, it should look like this

1
2
3
4
5

But instead I get

5
5
5
5
5

You could store your input parameters into ArrayList

public static void main(String[] args) {
    Scanner ns = new Scanner(System.in);
    int n = 0;
    int i = 1;
    List<Integer> params = new ArrayList<>();
    while (i <= 5) {
        System.out.println("enter a number");
        n = ns.nextInt();
        params.add(n);
        i++;
    }
    for (Integer param : params) {
        System.out.println(param);
    }
}

Output:

1
enter a number
2
enter a number
3
enter a number
4
enter a number
5
1
2
3
4
5

How do I make Java register a string input with spaces?, This loop prints out the numbers from 1 through 10 on separate lines. How does it work? Output: 1. 2 The while loop is the generic loop; every loop can be written as a while loop. The for loop the output stream. * @return int input from user. Java Loops: sum input values. Let see other Java code examples of using loops--for loop, while loop, and do while loop to enable a user to input a number of data points and then calculate the total of the data values. We provide three separate Java code examples to solve the same problem.

All the inputs are being printed, the problem is that the while loop sets n to the value of 5 and then you print 5 five times. The correct code you are looking for is:

int n = 0;

int i=1;  
while(i<=5)
{  
  System.out.println("enter a number");  
  n = ns.nextInt();
  i++;  
  System.out.println(+n);
}

Java For Loop, Most computations require different actions for different inputs. The three operands are separated by the ? and : symbols. Also estimate the most common outcome (record the frequency counts for 2, 3, and 4 children, and also for 5 and  Java Example to break integer into digits. Here we are using Scanner class to get the input from user. In the first while loop we are counting the digits in the input number and then in the second while loop we are extracting the digits from the input number using modulus operator.

Please print number in loop. See code below :

   Scanner ns = new Scanner(System.in);
    int n = 0;

    int i=1;  
    while(i<=5)
    {  
    System.out.println("enter a number");  
    n = ns.nextInt();
    System.out.println(n);
    i++;  
    }  

[PDF] Java Loops and Methods, A Java program takes input values from the command line and prints a string of input stream that contains a sequence of values separated by whitespace. Solution: interview for N/2 minutes and record the rating of the best like the one below using a nested for loop and many calls to StdDraw.point(). Typically, you read data from the line in a loop, as in this example. Within the while loop, each chunk of retrieved data is processed in whatever way is appropriate for the application—here, it's written to a ByteArrayOutputStream. Not shown here is the use of a separate thread to set the boolean stopped, which terminates

Conditionals and Loops, Instead we use the for-keyword to iterate over each element in a collection. currentTimeMillis(); // Version 1: loop over each array separately. for (int i = 0;  Java ArrayList for loop for each example shows how to iterate ArrayList using for loop and for each loop in Java. It also shows how to use the ArrayList size to loop through the elements of ArrayList.

1.5 Input and Output, Here by writing Scanner s, we are declaring s as an object of Scanner class. System.in within the round brackets tells Java that this will be System Input i.e. input  A Computer Science portal for geeks.

Comments
  • Move the System.out.println(n) statement inside the while loop. Or store the input in a map in the while loop and print the contents of the map afterwards. Your variable n is overridden each time inside the while loop, so afterwards it only contains the latest value.
  • What you are doing in here is updating the value of same variable(storage space) in the loop. You would need 5 separate storage spaces to save the values of variables.
