when memory overflow or no available memory is provided to the garbage collector, the Java virtual machine cannot allocate an object, and this exception is thrown
we know that vector uses an object array to store its elements (protected object [] elementdata;), When elementdata. Length() is too large, the JVM can't allocate so much memory space, and an error will occur. You can try to define int [] a = New Int [100000000] (381m), and the same problem will appear
