How to Convert Int to Long in Java? Integer to Long Program
In numeric data, two frequently used data types are int and long. While both are integral types, they possess distinct characteristics that make them suitable for different use cases.
In this post, we will learn how to convert int to long in Java. The int data type, a 32-bit signed integer, is well-suited for a vast range of general-purpose calculations. On the other hand, the long data type, with its 64-bit signed integer representation, extends the numerical range significantly, allowing for handling more substantial numerical values.
Understanding the skills of converting int to long in Java programming is essential, as it goes beyond a simple data type casting operation. We will explore the implications of such conversions, including the potential for data loss due to narrowing and the significance of handling integer overflow gracefully.
The ability to convert between numeric types with confidence is crucial in various domains, including scientific computations, financial applications, and working with large datasets.
Convert Int to Long in Java
You can convert an integer to a long in Java language using a process called "widening" or "implicit type conversion." This conversion is safe because a long can hold a larger range of values than an int.
Code
int intValue = 42;
long longValue = intValue; // Implicit conversion from int to longOutput
42Explanation
In the example above, we have an int variable named intValue with a value of 42. By directly assigning this int value to a long variable longValue, Java automatically performs the conversion from int to long.
Keep in mind that widening conversion is safe when converting from a data type with a smaller range (like int) to a data type with a larger range (like long). However, narrowing conversion (converting from a larger data type to a smaller data type) may result in data loss or truncation if the value is outside the range of the target data type.
