Your question: Can you compare int to long in Java?

Yes, that’s fine. The int will be implicitly converted to a long , which can always be done without any loss of information. You can compare long and int directly however this is not recommended.

How does int compare to long?

If counted in bytes, int is 4 bytes. If counted in bytes, long is 8 bytes. In Java the range of type int is –2,147,483,648 to 2,147,483,647. –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.

How do you compare long in Java?

equals() is a built-in function in java that compares this object to the specified object. The result is true if and only if the argument is not null and is a Long object that contains the same long value as this object. It returns false if both the objects are not same.

Can I use long instead of int?

The typical thing to do is to just use int if you don’t care about the size of the integer. If you need a 64-bit integer, then you use long . If you’re trying to use less memory and int is far more than you need, then you use byte or short .

Can we use == to compare long in Java?

equals() compares values. These two Longs are objects, therefore object references are compared when using == operator. However, note that in Long id1 = 123L; literal value 123L will be auto-boxed into a Long object using Long.

Why do we use long int?

Sometimes, the range of long is the same as int (32-bit systems; 64-bit Windows); then the main reason for using long or int is to match the interface to a particular API (because the types are still distinct, even if they support the same range).

What is difference between long int and long long int?

long and long int are identical. So are long long and long long int . In both cases, the int is optional. As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long .

How do you convert long to int?

Let’s see the simple code to convert Long to int in java.

  1. public class LongToIntExample2{
  2. public static void main(String args[]){
  3. Long l= new Long(10);
  4. int i=l.intValue();
  5. System.out.println(i);
  6. }}

Can long be null Java?

As primitives(long) can’t be null,It can be converted to wrapper class of that primitive type(ie. Long) and null check can be performed.

How do you compare two wrapper classes in Java?

Comparing Integers

Integer is a wrapper class of int, and it provides several methods and variables you can use in your code to work with integer variables. One of the methods is the compareTo() method. It is used to compare two integer values. It will return a -1, 0, or 1, depending on the result of the comparison.

Is Long Long faster than int?

1 Answer. This question is impossible to answer universally in a sense whether long is faster than int . The code could be ran on a 16-bit platform with 32-bit long and 16-bit int on which the int would probably be faster – but not necessarily.

When should I take long long int?

The long long takes twice as much memory as long. In different systems, the allocated memory space differs. On Linux environment the long takes 64-bit (8-bytes) of space, and the long long takes 128-bits (16-bytes) of space. This is used when we want to deal with some large value of integers.
