Explanation:
class TestScores {
double test1;
double test2;
double test 3;
public TestScores (double test1, double test2, double teat3){
this.test1= test1;
this.test2 = test2;
this.test3 = teat3;}
//mutator
public setTest1(double test1){
this.test1 = test1;
}
//accessor
public double getTest1(){
return test 1;
}
//Write same accessors and mutators for test2 and test3
public double getTestAverage(){
double sum = test1+test2+test3;
return sum / 3;
}
}
class TestRun{
public static void main (String [] args){
TestScores scores = new TestScores(50.5, 40.0, 80.7)
int average = scores.getTestAverage();
System.out.print(average);
}
