在Eclipse中,鼠标选中或者光标移动到java类的变量名时,相同变量会被标识显示(设置背景色高亮),
并且侧边滚动条会标出变量的位置, 查找变量十分方便。
1.相同变量标识高亮显示:
Window ->preferences ->Java ->Editor ->Mark Occurrences
勾选复选框 Mark occurrences of the selected element in the current file

2.设置标识显示的高亮背景颜色:
Window -> preferences -> General -> Editors -> Text Editors -> Annotations
右边列表选择Occurrences,点击Color设置高亮背景颜色。
