Is it possible in any Java IDE to collapse the type definitions in the source code?
- by asmaier
Lately I often have to read Java code like this:
LinkedHashMap<String, Integer> totals = new LinkedHashMap<String, Integer>(listOfRows.get(0))
for (LinkedHashMap<String, Integer> row : (ArrayList<LinkedHashMap<String,Integer>>) table.getValue()) {
for(Entry<String, Integer> elem : row.entrySet()) {
String colName=elem.getKey();
int Value=elem.getValue();
int oldValue=totals.get(colName);
int sum = Value + oldValue;
totals.put(colName, sum);
}
}
Due to the long and nested type definitions the simple algorithm becomes quite obscured. So I wished I could remove or collapse the type definitions with my IDE to see the Java code without types like:
totals = new (listOfRows.get(0))
for (row : table.getValue()) {
for(elem : row.entrySet()) {
colName=elem.getKey();
Value=elem.getValue();
oldValue=totals.get(colName);
sum = Value + oldValue;
totals.put(colName, sum);
}
}
The best way of course would be to collapse the type definitions, but when moving the mouse over a variable show the type as a tooltip. Is there a Java IDE or a plugin for an IDE that can do this?
