Break or return from Java 8 stream forEach?
Feb 07, 2025 pm 12:09 PM
Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation?
Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems.

Understand Stream forEach
The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is
Java Program to Find the Volume of Capsule
Feb 07, 2025 am 11:37 AM
Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods.
Capsule volume formula
The formula for capsule volume is as follows:
Capsule volume = Cylindrical volume Volume Two hemisphere volume
in,
r: The radius of the hemisphere.
h: The height of the cylinder (excluding the hemisphere).
Example 1
enter
Radius = 5 units
Height = 10 units
Output
Volume = 1570.8 cubic units
explain
Calculate volume using formula:
Volume = π × r2 × h (4
