The “program documentation” refers to Oracle Java SE`s licensing information manual for the corresponding version that is available under www.oracle.com/java/technologies/javase-documentation.html and any documentation provided by Oracle with the programs or under docs.oracle.com/en/java. “Oracle Approved Product Use” refers to your internal use of programs only for execution: (a) products identified as Schedule A products at java.com/oaa; and/or (b) software applications designed using products identified as Schedule B products on java.com/oaa by an Oracle licensee of these Schedule B products. If you`re not sure if the app you want to run with the programs is developed with a Schedule B product, please contact your application provider. There are many principles that you must adhere to when programming in Java or in programming languages. The principles depend on the programming language you use. You can learn more about the contract in Design by Contract Wikipedia page A common example of a java contract is to replace equals () if hashCode () is replaced. Two objects considered identical must have the same harbour code contractually. It is possible to write code that is syntically correct, that does not obey this, but it may not work properly, and it is the fault of the programmer who broke the contract. Oracle Cloud Infrastructure Use (“OCI Use”) refers to your use of programs in Oracle`s cloud infrastructure with Oracle Cloud Infrastructure products in Oracle PaaS and IaaS Universal Credits service descriptions, which are available at oracle.com/contracts during the period during which you keep a subscription to these Oracle Cloud infrastructure products. .
. . “Application” refers to applications that need to be run on the Java platform, Standard Edition. . Normally, we do not write the implementation of these methods by hand. As you can see, there are a whole series of traps. Oracle continued to offer free use of Java SE under the Oracle Binary Code License (OBCL) agreement, as it acquired Sun Microsystems. This use was limited and free only if certain conditions were met . .
. . Oracle`s licence fees and limitations grant you a limited, non-exclusive, non-negotiable and limited license for program use, subject to the limitations mentioned in this Agreement and in program documentation; Only for: Please note that the Oracle OpenJDK under the Open Source GNU General Public License v2, with the Classpath Exception (GPLv2-CPE) (from Java 9) and the Oracle Java SE (including Oracle JDK for Java 8 and over and Oracle JRE with Java Web Start in Java 8) remains free under the OTN license agreement for Java SE for personal use, development, and prototyping. “Separate Terms” refers to the separate licensing terms in the program documentation, reads or notification files that apply to separate licensed third-party technologies. Use the query setting below to use the zus. indicate by the customer that you are confirming. It is interesting to note that EqualsVerifier tests both equals () and hashcode () methods. Let`s make sure that our team class follows the Equals () and hashCode (): A common method is to have the Equals () and hashCode () methods generated from our IDE.
The second criteria of the hashCode method contract have an important consequence: if we are to replace equals (), we must also replace hashCode ().
