I am trying to build android apk for my application. I have successfully installed java jdk1.7.0_79, using these Instructions (in highest voted answer). My O.S. is Ubuntu 15.10.
When I build apk using both the Jdk (jdk1.7.0_79/80) I get same build error

Note
1) I have updated jdk location after installing each jdk(by removing previously installed jdk), I have no problem in java installation.
2) I have previously resolved rendering error in layout which is also same as "Unsupported major.minor version 52.0" by unchecking Android API 23:N(preview).
Check if your build.gradle(Module:app) has compile
eg:
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

I have a spring boot REST API jar file which works perfectly fine when I run it in my local machine using eclipse IDE, however when I upload the jar file to my VPS server I get the following error:

I changed the java version in my POM file from version 11 to java 8:
<properties>
<java.version>8</java.version>
</properties>
In the VPS server I could see that the available java versions are: java 7 (Version : 7u80) and java 8 (Version : 8u92 - 1.8.0_92-b14), however my JRE version is jre 1.8.0_201.
If I keep java 7 in the VPS server I get the exception mentioned above and if I remove java 7 from the VPS server, then I get the following error when trying to run the jar file from ssh using Putty:
[root#vps public_html]# java -jar SpringBootProject-0.0.1-SNAPSHOT.jar
-bash: java: command not found
[root#vps public_html]#
How do I fix this?

How to fix the error ?
I am trying to build my apk in Unity (2017.3.0f3) but I get the error Unsupported major.minor version 52.0. I have read elsewhere that to fix this download Java JDK 8 and select the path. I have done this with different version of Java 8 and none of them are working. I have tried updating all my android SDK packages but Unity wont build on the latest SDK tools so I had to replace them with the Revision 25.2.5 (January 2017) tools as specified in the following unity answers page:

I am at a loss now, any advice is appreciated. Thanks.

I managed to solve this issue by changing the unity build system from internal to Gradle in the build settings
A teacher of mine created a program on java around 2005, he has always used MacOS. He sent the .jar to me and a classmate, both linux (me Debian 8 and him Ubuntu) and we can't execute the program because it returns a lot of exceptions.
At first I thought it could have been because the program was too old but my teacher can run it in his 1 year old updated mac perfectly fine.
Checked and Debian comes with OpenJDK as default. Havent installed anything, is there anything I should be installing for it to run?
PS: if I double click the .jar I can see the folders.
The exceptions are:

I don't know anything about java so please if you can try to be as basic as you can. I am also new to Debian, so I really don't know if there's a package missing from the default installation.
Edit:
The MANIFEST.MF file is
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.2
Created-By: 1.6.0_24-b07-334-10M3326 (Apple Inc.)
Class-Path: lib/Jama-1.0.2-ed.jar lib/jfreechart-1.0.6.jar lib/ant.jar
lib/jcommon-1.0.10.jar
X-COMMENT: Main-Class will be added automatically by build
Main-Class: com.cmcweb.electronicstructure.CompleteDOSPlotter
You have to download JFreeChart.jar libary (http://www.java2s.com/Code/Jar/j/Downloadjfreechartjar.htm) because your teacher didn't include external classes in his jar file.
Put JFreeChart.jar into /your_linux_path/jre/lib/ext folder and after that it should works.
P.S. The same you have to do with Jama.jar and jcommon.jar
Make sure you have all jars with the version from the manifest file downloaded in a lib directory. Lib directory should be placed in the same directory as your jar, the names of dependency jars should be exactly the same as these from classpath in manifest.
So in your case, it may not work with the newest JFreeChart version. You need to find and download version 1.0.6
Am attempting to compile the kafka sample from here in IntelliJ. After much fussing with dependencies have run into this issue that I can't seem to get past:

I've run across a few notions that suggest this is an issue with the scala version. Current library list:
flink-runtime-1.0-SNAPSHOT
flink-streaming-java-1.0-SNAPSHOT
flink-connector-kafka-1.0-SNAPSHOT
flink-java8-1.0-SNAPSHOT
flink-core-1.0-SNAPSHOT

flink-clients-1.0-SNAPSHOT
org.apache.kafka:kafka-clients:0.8.2.2
org.apache.kafka:kafka_2.11:0.8.2.2
flink-optimizer-1.0-SNAPSHOT
org.apache.sling:org.apache.sling.commons.json:2.0.6
de.javakaffee:kryo-serializers:0.28
com.github.scopt:scopt_2.11:3.3.0
org.clapper:grizzled-slf4j_2.9.0:0.6.6
com.typesafe.akka:akka-osgi_2.11:2.4.0
com.typesafe.akka:akka-slf4j_2.11:2.4.0
Suggestions on where I've run astray?
The problem is indeed a Scala version mismatch. You're mixing dependencies which are built for Scala 2.11, e.g. org.apache.kafka:kafka_2.11:0.8.2.2 with Flink dependencies which are built by default for Scala 2.10.
One of the dependencies built for Scala 2.11 pulls in the scala-library:2.11 jar which replaces the scala-library:2.10 dependency required by the Flink dependencies. You either use the binaries built for Scala 2.10 for the non-Flink dependencies or you build and install Flink using Scala 2.11. See https://ci.apache.org/projects/flink/flink-docs-master/setup/building.html#build-flink-for-a-specific-scala-version for how to build Flink with different Scala version.
Kafka example
If you just want to bump the version of the referenced Kafka example to 0.10-SNAPSHOT you have to change the Flink version in the pom.xml file and you have to use the FlinkKafkaProducer instead of the KafkaSink in the WriteIntoKafka.java file. You don't need the SimpleStringSchema then anymore. That is all you have to change (no additional dependencies are required).
