Sort a HashMap by Keys in Java Using the keys, we can sort a HashMap in two ways: aLinkedHashMapor aTreeMap. While using theLinkedHashMapapproach, it is vital to obtain a key set. Upon receiving such a key set, we translate these into a list. This list is then sorted accordingly...
In this code, you use theprintln()method to print the second element of thepasswordarray. (For more on theSystem.out.printlnstatement, check out our tutorialHow To Write Your First Program in Java.) The second element has an index of1because array elements are numbered starting at 0, as ...
Within this loop, the value of the current element (array[i]) is assigned tokey, andjis set to the previous index (i - 1). The next step involves awhileloop to compare the key with elements in the sorted portion of the array (array[0..i-1]). ...
