Doubt about to verify one array in java

Question

hi people i want to verify the elements of one array and show element at element if true or false in enside of one limited ex 10at100
this my function

public static boolean entre10e100(int v[]) {
for (int i = 0; i < v.length; i++) {
if (v[i] > 10 || v[i] < 100) {
if(i == v.length){
return true;

}
}else{
return false;
}
}

Answer 1

add to the end of your method return true;
although the program never gets there - it always gets to one of your return statements, but the compiler doesn't know this, so you get compile error
if the lengthnof your array was 0, the program would never reach any return statement

Answer 2

and change if (i==v.length) to (i==v.length-1), because v.length -1 is the index of last element
