Released in July 2011, Java 7 introduced game-changing features: try-with-resources, the diamond operator (<>), strings in switch statements, and the Files API (NIO.2). By April 2015, Java 7 reached its End of Public Updates. The last free public update was JDK 7u80 (released April 14, 2015).
Warning: Oracle no longer hosts JDK 7u80 publicly on its main website. However, it remains in the java-archive section for developers with an Oracle account.
JDK 7 Update 80 holds a special place in Java history. Released in April 2015, it was the last public release of Java 7 before Oracle moved it into "End of Public Updates." This means it was the final version freely available for commercial use without a paid support contract from Oracle. For many enterprises, this became the "golden standard" for Java 7 stability.
