Java工程師的工資待遇怎么樣?

Java工程師的工資待遇怎么樣?

Java軟件工程師一般月薪范圍在4000-10000元，遠(yuǎn)遠(yuǎn)超過了應(yīng)屆畢業(yè)生月薪 2500元的平均水平。通常來說，有一年工作經(jīng)驗(yàn)的Java高級(jí)軟件工程師的薪酬大致在年薪10—13萬左右。

從Java的應(yīng)用領(lǐng)域來分，Java語言的應(yīng)用方向主要表現(xiàn)在以下三個(gè)方面：首 先是大中型的商業(yè)應(yīng)用;其次是桌面應(yīng)用，就是常說的C/S應(yīng)用;再次是移動(dòng)領(lǐng)域應(yīng)用。
