在Java中,可以使用以下幾種方法來拋出異常:
throw new Exception("This is an example of throwing an exception");
public void doSomething() throws IOException {
// code that may throw IOException
}
try {
// code that may throw an exception
} catch (Exception e) {
// handle the exception
}
try (FileInputStream fis = new FileInputStream("file.txt")) {
// code that may throw an IOException
} catch (IOException e) {
// handle the IOException
}
這些是在Java中拋出異常的幾種常見方法,可以根據具體的需求選擇適當的方式來處理異常。
