I'm trying to write a while loop that accepts the input from the user and the test if it's positive or negative.

Answer 1

import java.util.Scanner;

class MyClass {
public static void main(String[ ] args) {
int a;
Scanner myVar = new Scanner(System.in);
a=myVar.nextInt();
while (a>0) {
System.out.println("Your input is postive");
break;
}

}
}

Answer 2

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int count;
System.out.println("Enter your value:");
count = scan.nextInt();
if(count <= 0){
while (count <=0) {
System.out.println("Negative value \nEnter positive value:");
count = scan.nextInt();
}
}
System.out.println("Positive value!");
}
}

Answer 3

why with while loop, try if block
if(x<0)
cout << "negative value" << endl;
else
cout << "positive value" << endl;
where x is your input
using while
while(x<0){
cout << "negative valu";
break;}
while(x>0){
cout << "positive value";
break;
}
you can also use flag variable method. But it will make you idiot.

Answer 4

Answer 5

I have shown example of while loop

Answer 6

You wrote if else statements I was looking for something like this, but mine not working
import java.util.Scanner;

class MyClass {
public static void main(String[ ] args) {
Scanner myVar = new Scanner(System.in);

while (myVar > 0 ) {
System.out.println("Your input is postive") ;
Else
System.out.println("put a positive number")
}
System.out.println(myVar.nextLine()); // help me fix it
}
}

Answer 7

in while loop use break after printing your value is positive,otherwise it is an infinite loop.
