Oct 23, 2023 · This guide will provide a comprehensive understanding of the long data type in Java, from its basic usage to more advanced techniques. We’ll explore everything from declaring and initializing long variables, performing basic operations, to more complex uses such as using it with arrays, in methods, and with the Long wrapper class.

Nov 19, 2015 · Use "L" to make it as long type. By default all integer type variable (byte,int,long) is "int" or. Use. long number = 600851475143L; See similar questions with these tags.

Nov 11, 2012 · With this example we are going to demonstrate how to use a long type in Java. The long data type is a 64-bit signed two’s complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). Use this data type when you need a range of values wider than those provided by int.

How to declare, initialize, and update a long variable. Maximum and minimum values a long data type can allow. Printing a long value to the console output. Performing arithmetic and bitwise operations on long values. Converting between long and other primitive data types. Using the Long class for additional operations.

The long keyword is a data type that can store whole numbers from -9223372036854775808 to 9223372036854775808. Note that you should end the value with an "L": Read more about data types in our Java Data Types Tutorial. Java Keywords.

The long keyword in Java is a primitive data type that represents a 64-bit signed two's complement integer. It is used when a wider range than int is needed. The long data type can store values from -2^63 to 2^63-1.

The long keyword is used to declare a variable as a long primitive type. The long primitive type is a signed 64-bit type and is useful for those occasions where an int type is not large enough to hold the desired value.

Feb 22, 2025 · Long is a primitive data type in Java that is used to represent signed 64-bit integers. Use data types that allow floating-point numbers, such as double or float, to store decimal values. If accuracy loss is acceptable, this mistake can be fixed by casting the decimal value to an integer type or by changing the data type of num to double or float.
