The most commonly used number systems are positional: Each number consists of a string of digits, and the value of that number is obtained by summing the digits multipled by a base to the exponent of the digit's position (from right to left, starting at 0).
For example, a number expressed as XYZ represents the value
3*(b^0) + 2*(b^1) + 1*(b^2)
b is called the radix. Its value is usually 10, but some other
values are commonly used, like 2 for binary numbers and 16 for hexadecimal numbers.

The first argument to parseInt is a string that represents
a number, such as "123". This string will be converted to its
integer value, i.e., 123.
The string should only contain digits, and letters only if the second argument is higher than 10.

The string should only contain digits, and letters only if the second argument is higher than 10.
If provided, the second argument to parseInt is the
radix to use to
convert the string. The radix must be between 2 and 36.
In this case, the value of 36 means that all 10 digits and 26 letters
are valid characters.
If the radix is not provided, the default value is 10. If the radix is greater than 10, then letters (case-insensitive) are treated as digits higher than 9 (A = 10, B = 11, and so on).

We're continuing to improve the format. We're studying how programmers use documentation to look for information, and how the presentation format can help or hinder their search. As part of this research, we're exploring and implementing new strategies to help present information more effectively.

Character.digit(char, int) returns a
nonnegative value), except that the first character may be an
ASCII minus sign '-' ('\u002D') to
indicate a negative value or an ASCII plus sign '+'
('\u002B') to indicate a positive value. The
resulting integer value is returned.

An exception of type NumberFormatException is

Examples:
parseInt("0", 10) returns 0
parseInt("473", 10) returns 473
parseInt("+42", 10) returns 42
parseInt("-0", 10) returns 0
parseInt("-FF", 16) returns -255
parseInt("1100110", 2) returns 102
parseInt("2147483647", 10) returns 2147483647
parseInt("-2147483648", 10) returns -2147483648
parseInt("2147483648", 10) throws a NumberFormatException
parseInt("99", 8) throws a NumberFormatException
parseInt("Kona", 10) throws a NumberFormatException
parseInt("Kona", 27) returns 411787

string literals in Java programs, such as "abc", are
implemented as instances of this class.
String class represents character strings. All
string literals in Java programs, such as "abc", are
implemented as instances of this class.
Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example:
String str = "abc";
is equivalent to:
char data[] = {'a', 'b', 'c'};
String str = new String(data);
Here are some more examples of how strings can be used:
System.out.println("abc");
String cde = "cde";
System.out.println("abc" + cde);
String c = "abc".substring(2, 3);
String d = cde.substring(1, 2);
The class String includes methods for examining
individual characters of the sequence, for comparing strings, for
searching strings, for extracting substrings, and for creating a
copy of a string with all characters translated to uppercase or to
lowercase. Case mapping is based on the Unicode Standard version
specified by the Character class.
The Java language provides special support for the string concatenation operator ( + ), and for conversion of other objects to strings. For additional information on string concatenation and conversion, see The Java Language Specification.
Unless otherwise noted, passing a null argument to a constructor
or method in this class will cause a NullPointerException to be
thrown.
A String represents a string in the UTF-16 format
in which supplementary characters are represented by surrogate
pairs (see the section Unicode
Character Representations in the Character class for
more information).
Index values refer to char code units, so a supplementary
character uses two positions in a String.
The String class provides methods for dealing with
Unicode code points (i.e., characters), in addition to those for
dealing with Unicode code units (i.e., char values).
Unless otherwise noted, methods for comparing Strings do not take locale
into account. The Collator class provides methods for
finer-grain, locale-sensitive String comparison.
javac compiler
may implement the operator with StringBuffer, StringBuilder,
or java.lang.invoke.StringConcatFactory depending on the JDK version. The
implementation of string conversion is typically through the method toString,
defined by Object and inherited by all classes in Java.or this further nested annotation!
