Java supports eight basic primitive data types. This tutorial explains basic primitive data types (int, long, short, byte, char, boolean, float, double) with their size, range and default value. Java basic data types are predefined and implicit to the la
In this example, we try to assign a value beyond the range of a data type. This leads to an arithmetic overflow. $ java Main.java 126 127 -128 -127 When an overflow occurs, the variable is reset to negative upper range value. Floating point numbers Real numbers measure continuous quantit...

Finally, the parallel collector is able to dynamically adjust its tunable parameters in response to the application's heap allocation behavior, leading to improved garbage collection performance over a wide range of applications and environments. This means less hand-tuning work for customers. This cap...
