Totally agree with Rima! But, if you want a bit more control over the process, maybe you want to do a custom implementation for converting int to binary in Java. You could manually construct the binary string using bitwise operations. Here’s an example that uses a StringBuilder to optimize performance:
public static String toBinary(int num) {
StringBuilder binary = new StringBuilder();
while (num > 0) {
binary.append(num % 2);
num /= 2;
}
return binary.reverse().toString();
}
int number = 156;
System.out.println(toBinary(number)); // Output: "10011100"
This gives you more flexibility—let’s say you want to tweak the formatting or convert to another base in the future. Also, by using StringBuilder, you avoid the inefficiency of string concatenation in loops, which can be costly performance-wise. It’s a solid choice when you need more customization!
