Looking for a free Java Compiler? You've come to the right place.
Java Runtime Environment application is free to download and offers easy-to-install, easy-to-use, secure, and reliable Browsers and Plugins applications. This application’s primary functions are comprehensive and go beyond the features offered by others that can be considered as its rivals. The essential download for Java applications. Java Runtime Environment or JRE is Java’s programming language. It’s really a type of virtual environment in which this programming language can run and it’s a required component whenever you do run a Java application. At PHONEKY Free Java Games Market, you can download mobile games for any phone absolutely free of charge. Nice graphics and addictive gameplay will keep you entertained for a very long time. At PHONEKY, you will find many other games and apps of different genres, from adventure and action to the logic and racing Java jar games.
Here are some of the compilers that I have personally used throughout my Java programming career. As I find others, I will of course try them out and then if I like it enough I'll put it up here as well. If you have a compiler you'd like to recommend, feel free to contact me in the Contact Us section of the site.
Note: No matter what compiler you get, you'll need the JRE (Java Runtime Environment). If you don't have the JRE, you may download it at Java.com. Once at the downloads page, it automatically selects what it thinks is the correct version for your system. That is probably the version you should go ahead and download.
Compilers
Eclipse - This is my favorite IDE. The tutorials on this site all use Eclipse as it is extremely user friendly and the best professional tool for beginners. When at the downloads page select Eclipse Classic if you want just the basic features that will run Java.
Netbeans - Another great IDE, and the one I used before I discovered Eclipse. I still have Netbeans and find it easy to work with, although it's not AS friendly as Eclipse. Still, it is a great tool for development. When you're at the download page, if you only want Java and none of the other features, make sure to download the Java SE bundle, the one that is 31 MB.
JGrasp - JGrasp is a basic Wordpad-like program that also can compile and run Java programs. This is a standard beginners compiler and used by many schools that teach Java. I'm not the biggest fan of this program although I used to use it before I discovered the power of true IDE's. I don't like JGrasp much because it isn't a professional tool used in the real-world, and is more for hobbyists and those learning. It also does not come with the JDK (Java Development Kit), so you'd have to download that separately if you don't already have it.
The full version string for this update release is 11.0.9+10 (where '+' means 'build'). The version number is 11.0.9.

Security Baselines
The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 11.0.7 are specified in the following table:
JRE Family Version = JRE Security Baseline (Full Version String)
- 11 = 11.0.9+7
- 8 = 1.8.0_271-b09
Oracle JDK Expiration Date
Oracle recommends that the JDK is updated with each Critical Patch Update (CPU). In order to determine if a release is the latest, the following Security Baseline page can be used to determine which is the latest version for each release family.
Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins. It is not recommended that this JDK (version 11.0.9) be used after the next critical patch update scheduled for January 19, 2021.

➜ Weak Named Curves in TLS, CertPath, and Signed JAR Disabled by Default
Free Java Download For Windows 10
- Weak named curves are disabled by default by adding them to the following disabledAlgorithms security properties: jdk.tls.disabledAlgorithms, jdk.certpath.disabledAlgorithms, and jdk.jar.disabledAlgorithms. The named curves are listed below.
- With 47 weak named curves to be disabled, adding individual named curves to each disabledAlgorithms property would be overwhelming. To relieve this, a new security property, jdk.disabled.namedCurves, is implemented that can list the named curves common to all of the disabledAlgorithms properties. To use the new property in the disabledAlgorithms properties, precede the full property name with the keyword include. Users can still add individual named curves to disabledAlgorithms properties separate from this new property. No other properties can be included in the disabledAlgorithms properties.
- To restore the named curves, remove the include jdk.disabled.namedCurves either from specific or from all disabledAlgorithms security properties. To restore one or more curves, remove the specific named curve(s) from the jdk.disabled.namedCurves property.
- Curves that are disabled through jdk.disabled.namedCurves include the following: secp112r1, secp112r2, secp128r1, secp128r2, secp160k1, secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1, sect163r1, sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1, sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, X9.62 c2tnb191v1, X9.62 c2tnb191v2, X9.62 c2tnb191v3, X9.62 c2tnb239v1, X9.62 c2tnb239v2, X9.62 c2tnb239v3, X9.62 c2tnb359v1, X9.62 c2tnb431r1, X9.62 prime192v2, X9.62 prime192v3, X9.62 prime239v1, X9.62 prime239v2, X9.62 prime239v3, brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, brainpoolP512r1
- Curves that remain enabled are: secp256r1, secp384r1, secp521r1, X25519, X448. See JDK-8233228
security-libs/org.ietf.jgss:krb5
➜ Support for Kerberos Cross-Realm Referrals (RFC 6806)
- The Kerberos client has been enhanced with the support of principal name canonicalization and cross-realm referrals, as defined by the RFC 6806 protocol extension.
- As a result of this new feature, the Kerberos client can take advantage of more dynamic environment configurations and does not necessarily need to know (in advance) how to reach the realm of a target principal (user or service).
- Support is enabled by default and 5 is the maximum number of referral hops allowed. To turn it off, set the sun.security.krb5.disableReferrals security or system property to false. To configure a custom maximum number of referral hops, set the sun.security.krb5.maxReferrals security or system property to any positive value.
