您不需要在类封装Example{}中使用类Test()

public class EncapsulationExample {
    private String name;
    private int x;

    public String getName() {
        return name;
    }
    public int getValue(){
        return x;
    }
    public void setName(String name){
        this.name = name;
    }
    public void setValue(int x){
        this.x = x;
    }
    public static void main(String[] args) {
        EncapsulationExample e1 = new EncapsulationExample();
        e1.setName("Aara");
        e1.setValue(10);
        System.out.println(e1.getName()+e1.getValue());
    }
}
