Do you need both 32 and 64 bit java?
If you have both 32 and 64 bit applications that use Java you need both. The Java plugins for browsers were only for 32 bit Java. Applets were on the way out by the time 64 bit browsers became a thing so the developers never bothered to do 64 bit versions of the plugins.
Why is java installing 32-bit?
In general 32-bit java is installed because many browsers are still 32 bit. This is changing allot with time, but for the longest time browsers stuck to being mostly 32-bit. 32-bit programs run fine on 64-bit operating systems.
How do I know if I have JDK 32 or 64 bit?

What is the difference between Java 32 bit and 64 bit?
As you have seen, the key difference comes in how much memory you can allocate, while 32-bit JVM can just have 4G which is very less for modern, memory-intensive Java application, 64-bit JVM virtually gives you unlimited memory.
Does Windows 10 need Java?

On most CPU architecures 32-bits is faster than 64-bit, all else being equal. 64-bit pointers require twice as much bandwidth to transfer as 32-bits. However, the x64 instruction set architecture adds a bit of sanity over x86, so it ends up being faster. The amount of handling of long types is usually small.
What are the benefits of 64-bit JVM?
The real advantage of the 64-bit JVM is that heap sizes much larger than 2GB can be used. Large page memory with the 64-bit JVM give further optimizations. The following graph shows the results running from 4GB heap sizes, in two gigabyte increments, up to 20GB heap.

Is 64bit Better than 32bit?
When it comes to computers, the difference between 32-bit and a 64-bit is all about processing power. Computers with 32-bit processors are older, slower, and less secure, while a 64-bit processor is newer, faster, and more secure.
Is x86 better than x64?
Older computers run on mostly x86. Today’s laptops with pre-installed Windows run mostly on x64. x64 processors work more efficiently than an x86 processor when dealing a large amount of data If you are using a 64-bit Windows PC, you can find a folder named Program Files (x86) on the C drive.
