如何从Java方法返回2个值
如果我们将一个对象传递给方法，然后修改它的值，那么方法可以给出多个值。参见以下示例–
示例
public class Tester {
public static void main(String[] args) {
Model model = new Model();
model.data1 = 1;
model.data2 = 2;
System.out.println(model.data1 + ", " + model.data2);
changeValues(model);
System.out.println(model.data1 + ", " + model.data2);
}
public static void changeValues(Model model) {
model.data1 = 100;
model.data2 = 200;
}
}
class Model {
int data1;
int data2;
}输出结果
1, 2 100, 200
