java錯誤Line nn: ";" expected處理方法：

1.這是因為字串換行了。有時你需要寫一個長字串。常見的錯誤是在字串中輸入了換行符。編譯器就會報錯：Line nn: ";" expected

2.當這種情況發生時, 解決方案是將字串拆分為兩個, 確保字串中都沒有新行, 並將它們與 + 連線起來。因此, 您可以替換:原來：String s = "A very long string which just happens to go over the end of a line and causes a problem with the compiler";修改後String s = "A very long string which just happens to go over the end "+"of a line and causes a problem with the compiler"

3.編輯器會提示：String literal is not properly closed by a double-quote

4.當我們編譯時，報錯

Example.java:4: 錯誤: 未結束的字串文字

String s = "A very long string which just happens to go over

^

Example.java:5: 錯誤: 需要";"

5.我們把多行拼接起來，再次編譯，就沒報錯了。
