java - Creating variables with names of strings -

i making api kind of thing school custom xml writer. have:

public document createdocument(int loops, int attr, string data[], string dataattr[][][]) {     document betterdoc = documenthelper.createdocument();     element root = betterdoc.addelement("root");     (int = 0; < loops; i++) {         element(object) data[i] = root.addelement(data[i])         (int i2 = 0; < attr; i++) {             .addatribute(dataattr[i][i2][0], dataattr[i][i2][1])         };     }      return betterdoc; } 

the line want is:

element(object) data[i] = root.addelement(data[i]) 

i want create element same name of data[i].

i using dom4j xml .jar in this, way.

i have heard of called hashmap , if correct method, please explain how use it.

you can't create dynamic variable unlike groovy, php or javascript, can create array or reuse existing variable:

with existing variable:

public document createdocument(int loops, int attr, string data[], string dataattr[][][]) {     document betterdoc = documenthelper.createdocument();     element root = betterdoc.addelement("root");     (int = 0; < loops; i++) {         element _data = root.addelement(data[i]);         (int i2 = 0; < attr; i++) {             _data.addatribute(dataattr[i][i2][0], dataattr[i][i2][1])         };     }         return betterdoc; } 

with array:

public document createdocument(int loops, int attr, string data[], string dataattr[][][]) {     document betterdoc = documenthelper.createdocument();     element root = betterdoc.addelement("root");     element[] _data = new element[loops];     (int = 0; < loops; i++) {         _data[i] = root.addelement(data[i]);         (int i2 = 0; < attr; i++) {             _data[i].addatribute(dataattr[i][i2][0], dataattr[i][i2][1])         };     }         return betterdoc; } 

you can replace array arraylist if prefer.
