3. Java Program to Compare Strings The following Java program compares two strings case-sensitively using thecompareTo()method. We ae using Hamcrest matches to assert the return values. Stringname="alex";//same stringassertThat(name.compareTo("alex"),equalTo(0));//Different casesassertThat(nam...
public CrunchifyComparable(String wordFromFile, int numberOfOccurrence) { super(); this.wordFromFile = wordFromFile; this.numberOfOccurrence = numberOfOccurrence; } @Override public int compareTo(CrunchifyComparable arg0) { int crunchifyCompare = Integer.compare(arg0.numberOfOccurrence, this.number...
Resize the window containing the table so that it's bigger than necessary to display the whole table. All the table cells become wider, expanding to fill the extra horizontal space. The table in SimpleTableDemo.java declares the column names in a String array: String[] columnNames = {"Firs...
and it can’t handle null values. If you try to sort a list with null values, it will throw aNullPointerException. Moreover, it may not work as expected with custom objects, unless the custom class implements theComparableinterface and overrides thecompareTo()method. ...

3. Final fields and Java records The component fields of a record are implicitly final, which means their values cannot be changed after the record instance is created. publicrecordTransaction(Stringid,doubleamount){// This won't compile - attempting to change a final field:publicvoidchangeAmount...

You can convert any data type to others using the asInstanceOf[] method.This method is derived from java.lang package, though it does not an import statement, but it will work on for java data types i.e. not all Scala types can be converted using this method....
