How do I convert numbers to different bases in Java?

You can use the Integer class methods like Integer.toBinaryString() for binary, Integer.toOctalString() for octal, and Integer.toHexString() for hexadecimal.

Can you show me an example of converting a decimal number to binary?

Sure! Here's a simple example:

int decimal = 10;
String binary = Integer.toBinaryString(decimal);
System.out.println(binary); // Output: 1010

What if I want to convert a string representation of a number?

You can use Integer.parseInt() to convert a string to an integer first, then convert it to the desired base. For example:

String numberStr = "15";
int number = Integer.parseInt(numberStr);
String binary = Integer.toBinaryString(number);
System.out.println(binary); // Output: 1111
