Java Double.isInfinite() is a static method in the Java Double class that checks whether a given Java double value is positive or negative infinity. It is useful for detecting and handling overflow or mathematical results that exceed the finite range of floating-point values. Introduced in Java 2004 with Java 5, isInfinite() is essential for error handling in scientific, engineering, or financial applications where infinity might occur.
