Question

Answer the questions in this section based on the following statements:

EMPLOYEE_DETAILS [0] [0] = “John”

EMPLOYEE_DETAILS [0] [1] = “Doe”

EMPLOYEE_DETAILS [0] [2] = “0123456788”

EMPLOYEE_DETAILS [1] [0] = “Jane”

EMPLOYEE_DETAILS [1] [1] = “Doe”

EMPLOYEE_DETAILS [1] [2] = “0123569988”

Q.4.2.1 Consider the statements above, then draw a table to illustrate how the data provided will be stored in memory.

In case of any queries, please revert back.

By looking at the data given, we can say that This is stored in a 2D array of shape [2][3] and is of type String in JAVA.

Q 4.2.1 => In memory, if we consider a row-major Representation, we can say that the following is stored as.

MEMORY LOCATION	F_NAME	L_NAME	PHONE_NUMBER
1000	John	Doe	0123456788
2000	Jane	Doe	0123569988

So, memory is allocated Consecutively to different blocks. If the first block takes 999 bytes space at 1000 index, next block starts at 2000-2999.

Q. 4.2.2 => This is 2D array of strings with 2 rows and 3 columns.

String[][] EMPLOYEE_DETAILS=new String[2][3];

You can use this easily using :-

EMPLOYEE_DETAILS [0] [0] = “John”

EMPLOYEE_DETAILS [0] [1] = “Doe”

EMPLOYEE_DETAILS [0] [2] = “0123456788”

EMPLOYEE_DETAILS [1] [0] = “Jane”

EMPLOYEE_DETAILS [1] [1] = “Doe”

EMPLOYEE_DETAILS [1] [2] = “0123569988”
