Write a Java method called findDistinguishingChar that gets two String objects and returns the character whose frequency of occurrence in the two Strings differs the most. For example,

findDistinguishingChar$("$apple$",$ "pale"$)$ is letter $\text{'}$p$\text{'}$ since $\text{'}$p$\text{'}$ appears twice in "apple" and once in "pale". The rest of characters either don't appear in both strings or appear once.

findDistinguishingChar$("$banana$",$ "ban"$)$ is $\text{'}$a$\text{'},$ findDistinguishingChar$("$ban$",$ "banner"$)$ is either $\text{'}$n$\text{'},\text{'}$e$\text{'},$ or $\text{'}$r$\text{'}($all three outputs are acceptable b$/$c there is more than one correct answer.$).$
