Geah This homework is intended to get practice with ADTs and Space Matrices Vectors Below is a UML. for the Upper Triangular Matrix, specifications for the stage mapping sedan some extra method requirements. Note that this UTM is filled with Strings, nether than ints, and so should be all! Please implement the UTM according to the specs-feel free to base your work as the Lower Triangular Matrix from class! String den Array boolean equal Object) Check if two UTM's are equal UTM doel Create a copy of this UTM Constructors void setElement(introw, int col, String dista) String getement now, in col) String toString) UTM concatenate/UTM, UTM static method UTM largestCombo (UTM, UTM) static method Upper Triangular Matrix Storape Mapping Rules Using a D Amay (not an ArayList) if(ic) Map to the location i*(i+1)/2+] else The element SHOULD be null Method hints catenate UTM should take two UTMs arguments and return a UTM where all the new elements are the old elements concatenated soft's cell holds "Hello" and 2 holde "World", the new UTM should hello World LargestCombe should retum a new UTM which has the largest string for EACH cell. between the two UTM . settlement and getElement must work according to the storage mapping niles, as we sessed with lower Triangular matris Equals and Clone should be self-explanatory, BUT of the object for equals is not a UTM, return false automatically leString should print a string representation of the UTM Something like the following suffices "Hello World Hello Human" "Hello Frien! NULL "Hello Alien" "Hello Moto NULL NULL "Helle Hello" Submit Upload your code to the link on brightspace in your main roate objects from the class and call different method to show that it works Eduation
