与私有变量相关的表达式的非法开头
Illegal start of expression relating to a Private variable
我正在尝试 运行 我的 AP 计算机科学老师提供给我们的一个项目来检查我们的工作。我一直在尝试两个 类 让老师的代码工作但无济于事。问题是当初始化私有变量 n 时,它给我一个错误读取 "illegal start of expression." 任何帮助将不胜感激。
这是代码:
package eastersunday;
public class Easter
{
public static void main(String[] args)
{
private int n;
private int p;
/**
Constructs the date of Easter Sunday.
* @param year
*/
public Easter(int year)
{
int y = year;
int a = y % 19;
int b = y / 100;
int c = y % 100;
int d = b / 4;
int e = b % 4;
int g = (8 * b + 13) / 25;
int h = (19 * a + b - d - g + 15) % 30;
int j = c / 4;
int k = c % 4;
int m = (a + 11 * h) / 319;
int r = (2 * e + 2 * j - k - h + m + 32) % 7;
n = (h - m + r + 90) / 25;
p = (h - m + r + n + 19) % 32;
}
/**
Gets the month of Easter Sunday
@return month of Easter Sunday
*/
public int getEasterSundayMonth()
{
return n;
}
/**
Gets the date of Easter Sunday
@return date of Easter Sunday
*/
public int getEasterSundayDay()
{
return p;
}
}
试试这段代码,在 main 方法之外使用变量和函数
package eastersunday;
public class Easter
{
public static void main(String[] args)
{
}
private int n;
private int p;
/**
Constructs the date of Easter Sunday.
* @param year
*/
public Easter(int year)
{
int y = year;
int a = y % 19;
int b = y / 100;
int c = y % 100;
int d = b / 4;
int e = b % 4;
int g = (8 * b + 13) / 25;
int h = (19 * a + b - d - g + 15) % 30;
int j = c / 4;
int k = c % 4;
int m = (a + 11 * h) / 319;
int r = (2 * e + 2 * j - k - h + m + 32) % 7;
n = (h - m + r + 90) / 25;
p = (h - m + r + n + 19) % 32;
}
/**
Gets the month of Easter Sunday
@return month of Easter Sunday
*/
public int getEasterSundayMonth()
{
return n;
}
/**
Gets the date of Easter Sunday
@return date of Easter Sunday
*/
public int getEasterSundayDay()
{
return p;
}
}
我一眼就看出一个问题:你的代码中有一些悬空的括号。这使得你在 main 中声明了一些东西,你可能有意也可能没有,因为你没有用'}'关闭它。确保每个 { 都以 } 结尾,否则您的代码会给您一些错误。
