How do you compare two long values in Java?

How do you compare two long values?

so == operator will check equality of object references.

  1. type cast both objects into primitive values and compare (long)val3 == (long)val4.
  2. read value of object and compare val3.longValue() == val4.longValue()

Can we use == to compare long in Java?

== compares references, . 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.

How do you compare primitive long values in Java?

Compare two primitive long variables in java

  1. the == operator tells you if the two operands are the same object (instance).
  2. the . equals() method on Long tells you if they are equal in value.

How do you compare two long strings?

Compare two Strings in Java

  1. if (string1 > string2) it returns a positive value.
  2. if both the strings are equal lexicographically. i.e.(string1 == string2) it returns 0.
  3. if (string1 < string2) it returns a negative value.

How do we compare primitives to each other?

Primitives. Like in other languages, we can compare the values of primitives with the < , > , <= , and >= operator. The same problems of floating-point data types apply to them, so be aware. Also, boolean isn’t comparable except for equality with == and !=

What is difference between long and long in Java?

A Long is a class, or a reference type, defined in the standard library. It stores a reference to an object containing a value (a “box”). A long on the other hand, is a primitive type and part of the language itself. … We say that Long is the wrapper type for long , and objects of type Long are boxed values.

How do you compare values in Java?

To compare integer values in Java, we can use either the equals() method or == (equals operator). Both are used to compare two values, but the == operator checks reference equality of two integer objects, whereas the equal() method checks the integer values only (primitive and non-primitive).

What is long value in Java?

The long is a numeric data type in Java. This is also the primitive type. The long type takes 64 bits of memory. The maximum value that a long type variable can store is 9,223,372,036,854,775,807L. The minimum value is -9,223,372,036,854,775,808L.

How do you compare two primitive data types in Java?

== can only compare primitives of the same type. So this is a comparison between an int and an int (since int is the wider of the two). It is equivalent to the following more explicit code. int a = 3; byte b = 3; if (a == (int)b) { … }

Can we compare two strings using == in Java?

In String, the == operator is used to comparing the reference of the given strings, depending on if they are referring to the same objects. When you compare two strings using == operator, it will return true if the string variables are pointing toward the same java object. Otherwise, it will return false .
