JAVA

$-$

The program first reads integer certificateCount from input, representing the number of pairs of inputs to be read. Each pair has a string and an integer, representing the certificate's holder and level, respectively. One Certificate object is created for each pair and added to ArrayList certificateList. Output "Highest certificate level: $",$ followed by the highest level of all the Certificate objects and a newline.

Ex: If the input is:

$3$

Ben $7$ Tim $9$ Wei $1$

then the output is:

Highest certificate level: $9$

Note: The ArrayList has at least one element.
