Embedded Three Digit Numbers Sum in java

Embedded Three Digit Numbers Sum

A string S is passed as the input with numbers embedded in it. The program must print the sum of all three digit numbers embedded in the string. The program must print 0 (zero) if no three digit numbers are embedded in the string.

Input Format:
The first line will contain the string S.

Boundary Conditions:
Length of S is from 2 to 200

Output Format:
The sum of all three digit numbers embedded in the string.

Example Input/Output 1:

     Input:
                teamscored307runsin50oversinthe3rdmatch
    Output:
                307
   Explanation:
                307 is the only three digit number embedded. Hence the sum is also 307.

Example Input/Output 2:
Input:
ibought234chocolates45icecreams121sticks600combsand9545mouse

Output:
955

Explanation:
The three digit numbers embedded in the string are 234, 121 and 600. Hence sum is 955.(9545 is a four digit number and hence not considered).

 Example Input/Output 3: 
Input:
monkey70parrot40okay
Output:
0
Explanation:No three digit numbers embedded in the string
