This program needs to be written in Java. Along with NO For/while loops, and no methods.

The only way without a while loop and no method I can think of is use switch with every possible variation of the four digit binary which is 15.

Here is the starter code:

import java.util.Scanner;
public class MyClass {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int digit = sc.nextInt();
switch(digit) {
case 0000:
System.out.println("0");
break;
case 0001:
System.out.println("1");
break;
case 0010:
System.out.println("2");
break;
case 0011:
System.out.println("3");
break;
case 0100:
System.out.println("4");
break;

… (fill in other cases)

}
}
}

There might be a better way, but without loops or methods this is all I got.

Supplementary content SC is usually an important part of a webpage (but is not required for a page to receive a high or even hig

vredina [299]

Answer:

True

Explanation:

In a web page, there are two categories of content, they are, the main content and the supplementary content.

The main content holds the needed information of the web page and changes from page to page, while the supplementary content, as the name implies, supports the quality of the main content. It content can be duplicated in multiple pages and does not need a high rating to promote the quality of a web page.

Analog method is also known us

Andreas93 [3]

Hi there! Thank you for choosing Brainly to ask your question. I would be happy to assist you today by answering. You were a little bit unclear, but I hope this answers your question. - Analogue methods refer to all manual methods where no computers are used, but with the advent of digital computers the term analogue is also used for analogue methods of computing data. An analogue signal varies continuously, according to information, and thereby the data are represented in a continuous form.

This the code from the last post I did

Andrew [12]

import java.util.Scanner;

public class JavaApplication86 {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

int x = 0, c = 0, sum = 0;

while (true){

x = scan.nextInt();

System.out.println("You entered: "+x);

if (x == -1){

break;

}

sum += x;

c++;

}

System.out.println("The sum is "+sum);

System.out.println("You entered "+c +" numbers");

}

This works for me. Instead of subtracting one from c and adding one to sum, I used an if statement to break away from the while loop if the entered number is -1.
