    int max = vector[0];
    int school;
      for(int i=0; i<vector.length; i++){
        if(vetor[i] > vector[0]){

No, a method can return one and only one value. Fortunately that's all that's needed here since all you need to do is to have the method return the index of the max value just as it's already written to do. Once you have that, the calling code can easily get the max value from the array.

// in the main method
// assuming an int array called myArray
int maxIndex = maxOfaVector(myArray);
int maxValue = myArray[maxIndex];

Problems though:

  • Your code has a typo, if(vetor[i] should be if (vector[i]
  • And a logic error. In the same if boolean test, you should test if (vector[i] > vector[max]) not if (vector[i] > vector[0])
  • Also, you should test to make sure that the array has length > 0 first.
