In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list
In this article we show how to filter a list in Java. To filter a list in Java, we either use a for loop and an if condition or we utilize the stream's filter method. Filter a list of integersIn the first example, we filter a list of integers. ...

, leading to a potential loss of accuracy. the method we choose to convert a float to an int depends on how we want to handle that fractional portion. 3. methods of float to int conversion there are several methods for converting a float to an int in java. each method handles the ...
The above example can be updated to handle the EOFException in a try-catch block: importjava.io.DataInputStream;importjava.io.EOFException;importjava.io.FileInputStream;importjava.io.IOException;publicclassEOFExceptionExample{publicstaticvoidmain(String[] args){ ...
In this example, the “addInteger” method does not handle the exception and throws it to the caller using the throws keyword. Therefore the caller, “main”, has to handle the IllegalArgumentException using a try-catch block. Java Throw vs Throws The table below lists the difference ...
