我有一个类,在类中我有三个方法,它们执行相同的操作但提供不同的输入,所以我想知道是否有任何方法可以使其调用更小。
我的代码;
import javax.swing.JFileChooser;
import javax.swing.JOptionPane;
import javax.swing.JTextField;
import javax.swing.filechooser.FileNameExtensionFilter;
public class test {
public void methodclassA() {
int result = JOptionPane
.showOptionDialog(
null,
"How would you like you insert your data, manually or from a file? ",
"Inserting data", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, new String[] {
"Manual", "From a File" },
JOptionPane.NO_OPTION);
if (result == JOptionPane.YES_OPTION) {
// Going to call methodA from another class
}
if (result == JOptionPane.NO_OPTION) {
JTextField NameField = new JTextField();
Object[] message = { "Path location:", NameField };
int result2 = JOptionPane.showOptionDialog(null, message,
"Inserting data", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, new String[] { "Ok",
"Locate the file" }, JOptionPane.NO_OPTION);
}
}
public void methodclassB() {
int result = JOptionPane
.showOptionDialog(
null,
"How would you like you insert your data, manually or from a file? ",
"Inserting data", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, new String[] {
"Manual", "From a File" },
JOptionPane.NO_OPTION);
if (result == JOptionPane.YES_OPTION) {
// Going to call methodB from another class
}
if (result == JOptionPane.NO_OPTION) {
JTextField NameField = new JTextField();
Object[] message = { "Path location:", NameField };
int result2 = JOptionPane.showOptionDialog(null, message,
"Inserting data", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, new String[] { "Ok",
"Locate the file" }, JOptionPane.NO_OPTION);
}
}
public void methodclassC() {
int result = JOptionPane
.showOptionDialog(
null,
"How would you like you insert your data, manually or from a file? ",
"Inserting data", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, new String[] {
"Manual", "From a File" },
JOptionPane.NO_OPTION);
if (result == JOptionPane.YES_OPTION) {
// Going to call methodB from another class
}
if (result == JOptionPane.NO_OPTION) {
JTextField NameField = new JTextField();
Object[] message = { "Path location:", NameField };
int result2 = JOptionPane.showOptionDialog(null, message,
"Inserting data", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, new String[] { "Ok",
"Locate the file" }, JOptionPane.NO_OPTION);
}
}
}
例如,我在类中的三个方法是; methodclassA、methodclassB、methodclassC,所有这些都要求用户提供相同的输入,但每个方法都会调用不同类的不同方法。
提前致谢,我希望我已经清楚地解释了自己。
编辑:我之前忘了提及,我的主类中有三个按钮,它们分别调用这三个方法。例如我的按钮A调用方法类A,按钮B调用方法类B,按钮C调用方法类C。
最佳答案
您可以只在方法中提供一个输入开关,因此它会类似于
public void methodCaller(char aSwitcher) {
int result = JOptionPane.showOptionDialog(null, "How would you like you insert your data, manually or from a file? ", "Inserting data",
JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, new String[] { "Manual", "From a File" }, JOptionPane.NO_OPTION);
if (result == JOptionPane.YES_OPTION) {
switch(aSwitcher)
{
case 'A':
//Going to call methodA from another class
break;
case 'B':
//Going to call methodB from another class
break;
case 'C':
//Going to call methodC from another class
break;
default:
throw new IllegalArgumentExcpetion("No method defined for option" + aSwitcher);
}
}
else if (result == JOptionPane.NO_OPTION) {
JTextField NameField = new JTextField();
Object[] message = {"Path location:", NameField};
int result2 = JOptionPane.showOptionDialog(null, message, "Inserting data",
JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, new String[] { "Ok", "Locate the file" }, JOptionPane.NO_OPTION);
}
}
可能是更好的方法,但这至少可以节省所有代码重复。
然后调用只需进行这些替换
methodclassA(); -> methodCaller('A');
methodclassB(); -> methodCaller('B');
methodclassC(); -> methodCaller('C');
这样做的另一个优点是您可以添加“D”、“E”、“F”,您只需修改将这些大小写添加到开关即可。
