Write a java program to Count String Occurrences.

Obtain two strings from the user as input. Your program should count the number of occurrences of the second word of the second sentence in the first sentence as a output you need to find count string occurrences in a string.

Return the count as output. Note – Consider case.

The return type is the modified string.

Input and Output Format:

Input consists of two strings with the maximum size of 100 characters.

The output consists of a single string.

Refer sample output for formatting specifications.

Sample Input 1:

abc bcd abc bcd abc abc

av abc

Sample Output 1:

4

Sample Input 2:

ABC xyz AAA

w abc

Sample Output 2:
