A Java String Array is an object that holds a fixed number of String values. Arrays in general is a very useful and important data structure that can help solve many types of problems. It's simplicity on how to access contents through index makes it powerful yet user-friendly. Here are some examples on how to use String Array in Java.
The Java String replace method can be used to replace a character or a string sequence from an instance of a String, with a new value of character or a String sequence. This is very useful in problems that needs String manipulations. ...
Float is one of the most basic data type in Java for representing numerical values with decimal places. A common situation is when we want to convert a float value to String. Below are some examples on how to convert float to String in Java using two decimal places.
The substring method of String is very useful in Core Java Programming. It is a fundamental method in performing String manipulation. What it does is extract a sequence of characters from a String and return that as a new String object. This post will show examples on how to use the Java substring method.
There are cases where we need to guarantee the width of a String. If the width is less than the target, we can pad the String to meet the required length. Here are some example Java codes on how to Left Pad String With Spaces to guarantee the length of a String.
Here are some example Java codes on how to Left Pad String With Zeroes to guarantee the length of a String. For example, if there are only 3 characters in a String and we wish to have it 10 characters long, we need to pad 7 zeroes to the left of the String.
There are cases when we need to Convert a Java Integer To Fixed Length String. The logic should append a certain character, usually blank or zero, to fill the missing characters when the number of digits is less than the required number of characters.
The split method of the Java String class splits the given string into substrings given a delimiter. The result is an array of String. We may specify the maximum number of items returned by using specifying the limit. Java String Split Limit examples will be shown below.
The String.split() method splits a String into an array of substrings given a specific delimiter. If we know that each substring represents a number or an integer, we may prefer to convert the output of String.split() into an array of integer.
