how to iterate through maps in java code example
Example 1: java for map
Map<String, String> map = new HashMap<>();
for(Entry<String, String> entry:map.entrySet()) {
System.out.println("key: "+entry.getKey()+" value: "+entry.getValue());
}
Example 2: iterate through map
//traditional way (long)
for(map<string,int>::iterator it=m.begin(); it!=m.end(); ++it)
if(it->second)cout<<it->first<<" ";
//easy way(short) just works with c++11 or later versions
for(auto &x:m)
if(x.second)cout<<x.first<<" ";
//condition is just an example of use
