CODE ON JVM:
It is the tech meetup name Organized in YuniQ company
LOCATION:
YuniQ, 4th Floor, TICEL BIOPARK, 5, CSIR Rd, Phase II, Tharamani, Chennai, Tamil Nadu 600113
TOPICS DISCUSSED IN TECH MEETUP;
MULTI THREADING IN JAVA - Jenifar P Software developer in Guvi
GARBAGE COLLECTION IN JAVA - Karthik Junior developer in Kasa for soft source
MULTI THREADING IN JAVA:
It concentrate to run the multiple part of the program
Concurrency-> Ability of the system to handle the multiple tasks at same time
Daemon Thread:
It is the background thread helps execution of the other non daemon thread
It is low priority thread not affecting the JVM execution of the program
Dead Lock in java:
Multiple thread blocks each other while waiting for locks held by one another
--> Mutual execution:
Only one thread is run and allocate the space at a time of execution
--> Hold and Wait:
If programing contains one or more thread in dead lock function one thread is execute at once other thread are waiting for execution.
Race condition:
It access the two or more thread in shared data outcome is different while executing the shared data
Volatile:
It is the java variable used to ensure the visibility of the changes in multiple thread
Synchornization:
It control the access of shared resource while multi threading
It prevent the data inconsitency while changes happen to the same data and overcome the race condition concept in java
Thread Pool:
It manage the collection of thread design to execute the large number of task
It can reuse the space of the existing thread
Exception Thread:
It refers that unhandle exception occure in specific thread in program execution
If we not solve this problem the program get terminated or crash the other program execution
Watch Dog:
It is designed to monitored the health of the system processing and also it correct the problem when it occurs
Semaphore:
It control the access of shared resources by maintaining the count of permits.
It comes under the java.util.concurrent package and it used limited number of thread to access and change concurrently
Garbage Collection:
It is one of the part in java to monitor the memory allocation for the program execution
1. Heap memory:
It act as a main role in jvm mechanism to store the object and array while program execution
It maintain the creation and deallocation of the object space in memory
2. Application Throughput:
It measure the application to utilize the memory to preform the task in specific time
3. Latency Pause time:
It is duration during the program execution is delayed or halted
4. Memory Footprint:
It refers to the total amount of memory consumed by jvm and application execution
Types of Garbage collection:
1. Serial Garbage Collection
2. Parallel Garbage Collection
3. G1 Garbage Collection
4. CMS (Content Management System)
5. ZCC (Z Garbage collection)
After the technical content the code on jvm team conducting two games
Connection - > Using the couple of picture to predict the technical term related to computer science
Technical Quiz - > This Game related to the java concepts
Based upon the performance the conducting team provide the gifts for winners
After the meetup they give some memorable stickers about the code on jvm
