在Java面向对象编程中,类的属性(也称为成员变量)用于存储对象的状态信息。要设置类的属性,您需要遵循以下步骤:
public class MyClass { // 声明属性 private int myInt; private String myString; private boolean myBoolean; } public class MyClass { // 声明属性 private int myInt; private String myString; private boolean myBoolean; // 构造函数 public MyClass(int myInt, String myString, boolean myBoolean) { this.myInt = myInt; this.myString = myString; this.myBoolean = myBoolean; } } myInt属性的值,您可以使用以下代码:MyClass myObject = new MyClass(0, "Hello", true); myObject.myInt = 42; public class MyClass { // 声明属性 private int myInt; private String myString; private boolean myBoolean; // 构造函数 public MyClass(int myInt, String myString, boolean myBoolean) { this.myInt = myInt; this.myString = myString; this.myBoolean = myBoolean; } // getter和setter方法 public int getMyInt() { return myInt; } public void setMyInt(int myInt) { this.myInt = myInt; } public String getMyString() { return myString; } public void setMyString(String myString) { this.myString = myString; } public boolean isMyBoolean() { return myBoolean; } public void setMyBoolean(boolean myBoolean) { this.myBoolean = myBoolean; } } 现在,您可以使用getter和setter方法设置和获取属性值,如下所示:
MyClass myObject = new MyClass(0, "Hello", true); myObject.setMyInt(42); int myIntValue = myObject.getMyInt();
