如果语句忽略运算符？

Question

I'm trying to run an if statement inside of my for loop. However, it seems to be ignoring the operators...or something. I'm trying to get it to give the number of the question that contains the lowest total and the number that contains the highest total. Here are the methods:

This one keeps returning 10:

public int topRatedQuestion(){

    int answerTotal = 0;
    int highScore = 0;
    int topQuestion = 0;

    for(int i = 0; i < 10; i++){

         for(int j = 0; j < 10; j++){

              answerTotal = answerTotal + answerArray[i][j];      
          } //close for (j)

          if (answerTotal >= highScore){

               highScore = answerTotal;
               topQuestion = i + 1;
          }

    }//close for (i)
    return topQuestion;   
}

This one returns 1 everytime: .

public int lowRatedQuestion(){

    int answerTotal = 0;
    int lowScore = 1000;
    int lowQuestion = 0;

    for(int i = 0; i < 10; i++){

        for(int j = 0; j < 10; j++){

            answerTotal = answerTotal + answerArray[i][j];        
        }//close for (j)

        if (answerTotal <= lowScore){

            lowScore = answerTotal;
            lowQuestion = (i + 1);                
        }

    }//close for (i)

    return lowQuestion;

}

Answer 1

The error is occurring due to the fact that you are not refreshing the value of answertotal during the next iteration of the outer for loop. This is thus leading to the accumulation of the total from the previous row of the 2D-array. In order to correct the code initialize the answertotal variable between the for loops in this way:

for(int i = 0; i < 10; i++){
            int answertotal=0;

     for(int j = 0; j < 10; j++){
