You are tasked with designing a program that can accurately convert any decimal number to binary using Java programming. The program must utilize bitwise operators to achieve this goal. 
Your program must be able to handle input from users in the form of a decimal number and output the corresponding binary representation. The output should be in the form of a string, with each binary digit separated by a space. 
To test the accuracy of your program, try converting the decimal number 117 to binary. Your program should output: 
1 1 1 0 1 0 1 1

Sure, here's a Java program that converts decimal numbers to binary using bitwise operators:
```java
import java.util.Scanner;
public class DecimalToBinary {
 public static void main(String[] args) {
 Scanner sc = new Scanner(System.in);
 System.out.print("Enter a decimal number: ");
 int decimal = sc.nextInt();
 int binary[] = new int[32];
 int index = 0;
 while (decimal > 0) {
 binary[index++] = decimal & 1;
 decimal = decimal >> 1;
 }
 StringBuilder sb = new StringBuilder();
 for (int i = index - 1; i >= 0; i--) {
 sb.append(binary[i]).append(" ");
 }
 System.out.println("Binary representation: " + sb.toString());
 }
}
```
The program first prompts the user to enter a decimal number. It then creates an array to hold the binary digits and uses bitwise operators to convert the decimal number to binary. The program then constructs a string with each binary digit separated by a space and prints it to the console.
To test the program, you can enter the decimal number 117 when prompted. The program should output: `1 1 1 0 1 0 1 1`.

Can you explain the difference between static and non-static methods in Java?
user
Sure, in Java, a method can be either static or non-static. A static method is associated with the class as a whole, while a non-static method (also known as an instance method) is associated with an instance of the class.

When a static method is called, it is not tied to any particular object instance. This means that you can call a static method on the class itself, without creating an instance of the class first. A common example of a static method is the main() method of a Java program.

On the other hand, a non-static method is called on an instance of the class. This means that you must create an instance of the class before you can call any of its non-static methods.

In general, static methods are used for utility functions that do not depend on the state of any particular object instance, while non-static methods are used for operations that depend on the state of individual object instances.

Do you have any more questions about this topic?
