How to reduce CPU usage of Java application?

Similarly, if a developer chooses to use the older Hashtable over a HashMap, synchronization may needlessly consume clock cycles. Choose the wrong Java collection class, and application performance will suffer. Choose the correct collection classes, and your high Java CPU usage problems will disappear.

Why is Java taking so much CPU?

Java applications may take high CPU resources for many reasons: Poorly designed application code with inefficient or infinite loops. Inefficient algorithms (poor application logic) Recursive method calls (causing hundreds of recursions)
