[Java]Try Catch Finally用法

package test;

public class TryCatchFinally {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		int a = 0, b = 10; 

		try {//runtime Exception 執行程式碼才知道有錯，編譯會過
			System.out.println("b/a = " + b / a); // 任意數除0就會出錯
		} catch (ArithmeticException ae) {
			System.out.println("第1個例外");
			System.out.println(ae.toString()); // 印出錯誤內容
		} finally {
			System.out.println("一定會執行finally");

		}

		innerclass inclass = new innerclass();
		// inclass.MorethanfiveWillError(90); //會直接說編譯錯，可用try catch除錯 或改值
		try {
			inclass.MorethanfiveWillError(90);
		} catch (Exception SE) {
			System.out.println(SE.toString());
		}

	}

}

class innerclass {
	void MorethanfiveWillError(int index) throws Exception {//這個方法要說 會丟出例外
		if (index > 5) {
			throw new Exception("太神拉不能超過5"); // Checked的例外 =編譯前就會跳錯誤
		}
	}
}
