Comparing G1 collector to ParallelGC

Many Java programmers do not know that there are four different garbage collectors that are available. Most professionals only employ the default garbage collection method in JVM, which used to be the ParallelGC method. Here, we will especially discuss ParallelGC and compare it with G1GC, which becomes the new default garbage collector in the Java 9 package.
