Identify Java paid components installed on your device
Here is a detailed step-by-step guide that includes code snippets and example outputs on how to identify if Java or Java paid components are installed on a device:
Step 1: Check if Java is installed
To check if Java is installed on a device, you can use the following command in the terminal:
$ java -version
If Java is installed on the device, this command will display the version of Java installed. If Java is not installed, an error message will be displayed.
java version "1.8.0_292" Java(TM) SE Runtime Environment (build 1.8.0_292-b10) Java HotSpot(TM) 64-Bit Server VM (build 25.292-b10, mixed mode)
Step 2: Check if Java paid components are installed
To check if Java paid components are installed on a device, you can use the following command in the terminal:
$ java -XshowSettings:properties -version | grep -E '^(sun.|com.)'
If Java paid components are installed on the device, this command will display a list of Java properties, including the properties related to paid components. If there are no paid components installed, the command will return an empty result.

For example, if a device has the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files installed, the output of the command may include the following properties:
com.sun.security.enableCRLDP com.sun.security.enableAIAcaIssuers com.sun.net.ssl.checkRevocation com.sun.net.ssl.checkExtendedKeyUsage com.sun.crypto.provider.SunJCE com.sun.net.ssl.trustStore com.sun.security.enableOCSP com.sun.crypto.provider.AES
com.sun.crypto.provider.SunJCE property indicates that the SunJCE provider is installed, which includes the JCE Unlimited Strength Jurisdiction Policy Files. This is a paid component that requires a license from Oracle.
Note that the exact properties and keywords may vary depending on the version of Java and the specific paid component installed on the device.
