Answer:
Java provide all the ADTs you need,therefore you do not need to create any newones.
This statement is not true.
Explanation:
ADTs are those data types which we use but we didn't know their inner working that is how it is working what is happening inside.It is commonly used for Data Structures for example:- In stack we use push and pop operations to insert and to delete element from a stack respectively but we didn't know how it is happening inside.How the stack is implemented and etc.Java provides most of the ADT's but not all.

Answer:
def main():
name = input("What is your name? ")
if not name == "" or "":
age = int(input("What is your age? "))
print("Hello " + name + "! You were born in " + str(2021 - age))
main()
Explanation:
Self explanatory
The allocation methods define how the files are stored in the disk blocks.
There are three main disk space or file allocation methods:
1.Contiguous Allocation-in this scheme,each file occupies a set of blocks on the disk. For example if a file requires x blocks and is given a block y as the starting location,then the blocks assigned to the file be :x,y+1,y+2,......y+x-1.
This means that given the starting block address and the length of the file(in terms of blocks required) we can determine the blocks occupied by the file.
Advantages
-both the sequential and direct accesses are supported
-this is extremely fast since the number of seeks are minimal because of contiguous allocation of file blocks.
2.linked allocation-in this scheme,each file linked list of disk blocks which need not be contiguous disk blocks can be scattered anywhere on the disk.
Advantages
it is very flexible in terms of file size.file size can be increased easily since the system does not have to look for a contiguous chunk
of memory.
this method does not suffer from external fragmentation and it makes it relatively better in terms of memory utilization.
3.Indexed Allocation-in this scheme,a special block known as the index block contains the pointers to all the blocks occupied by a file.Each file has its own index block.the entry in the index block contains the disk address of the block
Advantages
it supports direct access to the blocks occupied by the file and therefore provides fast access to the file blocks
it overcomes the problem of external fragmentation.
