Each tuple provides utility methods to check their elements in similar fashion as collection. Example Let’s see JavaTuples in action. Here we’ll see how to check elements in a tuple. Create a java class file named TupleTester in C:\>JavaTuples. File: TupleTester.java Verify the result Compile the classes using javac compiler as follows − Now run the TupleTester to […]

Each tuple implements Iterable interface and can be iterated in similar fashion as collection. Example Let’s see JavaTuples in action. Here we’ll see how to iterate tuples. Create a java class file named TupleTester in C:\>JavaTuples. File: TupleTester.java Verify the result Compile the classes using javac compiler as follows − Now run the TupleTester to see the result […]

Tuple to List/Array A tuple can be converted to List/Array but at cost of type safety and converted list is of type List<Object>/Object[]. Collection/Array to Tuple A collection can be converted to tuple using fromCollection() method and array can be converted to tuple using fromArray() method. If size of array/collection is different than that of […]

A tuple has removeAtX() methods to remove value at particular index. For example Triplet class has following methods. Removing an element returns a new tuple. Example Let’s see JavaTuples in action. Here we’ll see how to remove value in a tuple. Create a java class file named TupleTester in C:\>JavaTuples. File: TupleTester.java Verify the result Compile […]

A tuple has add() method at the end of a tuple and it changes the type of tuple as well. For example adding a element to Triplet tuple will convert it to a Quartet tuple. A tuple has addAtX() methods as well to add a position at particular index starting from 0. A tuple can […]

A tuple has setAtX() methods to set value at particular index. For example Triplet class has following methods. Feature Example Let’s see JavaTuples in action. Here we’ll see how to set values in a tuple using various ways. Create a java class file named TupleTester in C:\>JavaTuples. File: TupleTester.java Verify the result Compile the classes using javac compiler […]

A tuple has getValueX() methods to get values and getValue() a generic method to get value by index. For example Triplet class has following methods. Feature Example Let’s see JavaTuples in action. Here we’ll see how to get values from a tuple using various ways. Create a java class file named TupleTester in C:\>JavaTuples. File: TupleTester.java […]

A tuple using JavaTuple classes can be created using multiple options. Following are the examples − Using with() Methods Each tuple class has a with() method with corresponding parameters. For example − Using Constructor Each tuple class has a constructor with corresponding parameters. For example − Learn Java in-depth with real-world projects through our Java certification course.
