如果你if條件不成立，你就沒有initialized max_nam 這個變數
請問你是否有在if以外的地方
有用到 max_nam 例如:輸出max_nam等等

小弟我剛碰JAVA, 今天在寫一個程式中想要印出一個字串
出現了variable might not have been instalized
就我所知...這種問題是出現在該變數沒有數值才會這樣嗎??
在這邊是想問 出現這種問題 大概是出了哪種的錯誤
順代一提 該字串已經被我定義過
附上簡略的程式碼
String max_nam, stu_nam;
int number, stu_scor, max_socr = 0;
number = MyInput.readInt();
for ( i = 0 ; i < number ; i++ )
{
stu_nam = MyInput.readString();
stu_scor = MyInput.readInt();
if ( stu_scor > max_scor )
{
max_scor = stu_scor;
max_nam = stu_nam;
}
}
這樣會出現max_nam might not have been instalized
