尝试在 Java 中计算 5 个数字的平均值时出现“非法的类型开头”

Question

I have test in Udacity Android developer

public class MyCalculator {

    int input1 = 10;
    int input2 = 20;
    int input3 = 30;
    int input4 = 40;
    int input5 = 50;

    public float average() {
        // TODO: write java code to calculate the average for all input variables

         return 0;
    }
}

I must give answer to continue study and I have been try everything and it did not accept the answer. It is expected that the method calculates a result of 30.0 as a float .

error :

|       public float average(( input1 + input2 + input3 + input4 + input5)/5 ) {
illegal start of type

|       System.out.print(average);
<identifier> expected

|       System.out.print(average);
<identifier> expected
