assume that the string oldstring contains at least 4 characters. a programmer is writing a code segment that is intended to remove the first two characters and the last two characters from oldstring and assign the result to newstring.

What is a Java String? A string is an object in Java that symbolizes a collection of characters or char values. A Java string object is created using the java.lang.String class.A String object can be created in one of two ways:using Java's string literal Double quotes are used to produce string literals.For instance: s="Welcome" string;
Using the keyword "new," a Java String can be produced.
For instance: String s=new String("Welcome"); This creates two objects—one in the heap and one in the string pool—as well as one reference variable, with the variable's' referring to the object in the heap.Let's now examine Java String pool in more detail.Java String Pool: Heap memory is used to store a collection of Strings as the Java String Pool. In this, the first thing the String Pool does after creating a new object is to determine whether or not the object is already in the pool. If it is, the variable receives the same reference back if not, a new object will be created in the String pool, and the appropriate reference will be returned. For better understanding, please see the diagrammatic representation.Two Strings, "Apple" and "Mango," were created using literal in the image above. Now, when the third String is created with the value "Apple," the existing object reference is returned rather than creating a new object. That is the rationale behind the introduction of the Java String pool.Before we continue, it's important to note that Strings in Java are immutable, unlike other data types. Immutable refers to the fact that Strings are constant; once they are created, their values cannot be altered. String objects can be shared because they cannot be changed. As an illustration:The following is the equivalent of the string str="abc":char data[] = 'a', 'b', 'c';
String str = new String(data);
Let's now examine a few of the built-in methods in the String class.To Learn more About newString refer To:

List advantages of using files to provide input and output
The advantages of using files to provide input and output are: when you open an output file, the application normally creates the file on the disk and allows it to write data to it. When you open an input file, the software may read data from it.
PL/I input and output commands (such as READ, WRITE, GET, and PUT) allow you to transfer data between a computer's primary and auxiliary storage. A data set is a collection of data that exists outside of a program. Input refers to the transmission of data from a data set to a program.
A computer file is a computer resource that stores data in a computer storage device and is recognized largely by its file name. Data may be written to a computer file in the same way that words can be written on paper.
