public class Test {public static void main(Stringlargs) {boolean leapYear; short year=2100; leapYear=(year%4==0&&year%100!=0)(year%400==0) if(leap Year) System.outprintln("2100是闰年。") else Systemoutprintln("2100不是闰年。"); }}这题的答案是多少

这段代码有语法错误,应该是这样的:
```
public class Test {
public static void main(String[] args) {
boolean leapYear;
short year = 2100;
leapYear = ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0));
if (leapYear)
System.out.println("2100是闰年。");
else
System.out.println("2100不是闰年。");
}
}
```
答案是:2100不是闰年。

public class Test{ public static void main(String[] args){ String s1 = "runoob"; String s2 = "runoob"; System.out.println("s1 == s2 is:" + s1 == s2);}}
The code you provided has a small mistake in the print statement. The expression `"s1 == s2 is:" + s1` is concatenated with `== s2` before being passed to `System.out.println()`. This causes a compilation error because you cannot concatenate a string with a boolean value directly.
To fix this, you need to use parentheses to group the concatenation expression properly. Here's the corrected code:
```java
public class Test {
public static void main(String[] args) {
String s1 = "runoob";
String s2 = "runoob";
System.out.println("s1 == s2 is: " + (s1 == s2));
}
}
```
In this corrected code, the expression `(s1 == s2)` is properly grouped and then concatenated with the string `"s1 == s2 is: "`.
public class test ( private static int j = 0; private static boolean methodB(int k) ( j += k; return true; ) public static void methodA(int i) { boolean b: b = i< 10 | methodB (4); b = i< 10 || methodB (8); ) publicstatic void main (String args[] } ( methodA (0); system.out.printIn(j); ) )为什么编译不通过
在提供的代码中,存在几个语法错误导致无法通过编译。以下是修复后的代码:
```java
public class Test {
private static int j = 0;
private static boolean methodB(int k) {
j += k;
return true;
}
public static void methodA(int i) {
boolean b;
b = i < 10 | methodB(4);
b = i < 10 || methodB(8);
}
public static void main(String[] args) {
methodA(0);
System.out.println(j);
}
}
```
修复的问题包括:
1. 类名应该首字母大写,所以将 "test" 改为 "Test"。
2. 方法的括号应该使用大括号 `{}`,而不是小括号 `()`。
3. `System.out.printIn` 应该是 `System.out.println`,其中 `l` 应该是小写字母。
4. `main` 方法签名中的参数列表应该是 `String[] args`,而不是 `String args[]`。
5. 方法调用应该使用 `.` 运算符,所以将 `methodA (0)` 改为 `methodA(0)`。
修复以上问题后,代码应该能够通过编译。
