oop - Java - sharing static methods across classes -


i've got 3 classes meant simulate mips32 pipeline registers. pretty this.

class idex {   public static map<string, integer> write;   public static map<string, integer> read;    static {     map<string, integer> tempmap = new hashmap<string, integer>();     tempmap.put("incrpc", 0);     tempmap.put("readreg1value", 0);     tempmap.put("readreg2value", 0);     tempmap.put("seoffset", 0);     tempmap.put("writereg_20_16", 0);     tempmap.put("writereg_15_11", 0);     tempmap.put("function", 0);     read = new hashmap<string, integer>(tempmap);     write = new hashmap<string, integer>(tempmap);   } }

i have utility methods copying data hashmaps , formatting/printing them.

how can share these methods across register classes? in general, possible share methods between classes work on respective static variables?
