A Java developer needs to estimate the amount of time needed for programming from the beginning to the completion of a project. Once a deadline is set, a developer must be able to deliver a product within a reasonable timeline. Since Java and other coding languages are consistently updated, Java developers need to be adaptable and ready to revise their work methods. Using this principle means Java developers create dependency objects as abstractions instead of specific items.
