我在介紹編程類,在我目前正在研究的實驗中,我們必須有兩個類並從一個類中提取方法,「能量」並讓它們運行「能源動力」。 我無法調用方法(testOne,testTwo,testThree)在爲「EnergyDriver」調用另一個類的方法
public class EnergyDriver
{
public static void main(String [] args)
{
System.out.println(mass1 + " kiolograms, " + velocity1 +
"meters per second: Expected 61250," + " Actual " + kineticE1);
System.out.println(mass2 + " kiolograms, " + velocity2 +
"meters per second: Expected 61250," + " Actual " + kineticE2);
System.out.println(mass3 + " kiolograms, " + velocity3 +
"meters per second: Expected 61250," + " Actual " + kineticE3);
}
}
public class Energy
{
public static void main(String [] args)
{
public double testOne;
{
double mass1;
double velocity1;
double holderValue1;
double kineticE1;
mass1 = 25;
velocity1 = 70;
holderValue1 = Math.pow(velocity1, 2.0);
kineticE1 = .5 *holderValue1 * mass1;
}
public double testTwo;
{
double mass2;
double velocity2;
double holderValue2;
double kineticE2;
mass2 = 76.7;
velocity2 = 43;
holderValue2 = Math.pow(velocity2, 2.0);
kineticE2 = .5 *holderValue2 * mass2;
}
public double testThree;
{
double mass3;
double velocity3;
double holderValue3;
double kineticE3;
mass3 = 5;
velocity3 = 21;
holderValue3 = Math.pow(velocity3, 2.0);
kineticE3 = .5 *holderValue3 * mass3;
}
}
你可以解析'能量'類到只是你試圖調用'EnergyDriver'方法的地方(反之亦然,無論是稱其他)。 – nhgrif
