Question: public static char[] upperCaseVersion ( char[] a) { char [] temp = new char [a.length]; char i; for (i = 0; i < a.length; i++)

public static char[] upperCaseVersion ( char[] a) { char [] temp = new char [a.length]; char i; for (i = 0; i < a.length; i++) temp[i] = Character.toUpperCase(a[i]); return temp; }

What is wrong with the following method definition? It is an alternate definition of the method by the same name defined in the previous subsection. It will compile. public static char [] upperCaseVersion( char [] a) { char i; for (i = 0; i < a.length; i++) a[i] = Character.toUpperCase(a[i]); return a; }
