1.Given a string of odd length, return the character in the middle of the string, so that "abc" yields 'b'.

middleChar("a") 'a' middleChar("abc") 'b' middleChar("abcde") 'c'

public char middleChar ( String str ) {

int m = str.length( )/2;

}

Given a string of odd length, return the string of length 3 from its middle, so that "Peach" yields "eac". Assume that the str length will be at least 3.

"and" middleThree("Peach") "eac" middleThree("Student") "ude"

public String middleThree( String str ) {

}
