When you create a SimpleDateFormat object, you specify a pattern String. The contents of the pattern String determine the format of the date and time. For a full description of the pattern's syntax, see the tables in Date Format Pattern Syntax.
The following code formats a date and time according to the pattern String passed to the SimpleDateFormat constructor. The String returned by the format method contains the formatted date and time that are to be displayed. Date today;
String output;
SimpleDateFormat formatter;
formatter = new SimpleDateFormat(pattern, currentLocale);
today = new Date();
output = formatter.format(today);
System.out.println(pattern + " " + output);
The following table shows the output generated by the previous code example when the U.S. Locale is specified:

All of the Java number classes have a parse[type] method, like parseInt() in Integer or parseDouble() in Double that convert Strings to primitive numbers. String s = getInput(); int var = Integer.parseInt(s);
To convert byte to String in java use the String(bytes, UTF-8); //example for one encoding type. You must know the special encoding that contains a variety of characters.
You can use the toUpperCase() method on a String to convert any String to all uppercase.
To convert a String object to lowercase in Java, use the toLowerCase() method. "HELLO".toLowerCase() returns a new String: "hello".
The import keyword in Java is used to tell the Java compiler where to find different classes and packages.java.util.Date is the location of the Date class: Date is a member of the util package, which is a member of the java package.

One can convert a string variable to an int variable in Java using the parse integer command. The syntax is int foo = Integer.parseInt("1234"). This line will convert the string in the parenthesis into an integer.

To convert string to int in Java, the easiest way is to simply use the method Integer.parseInt(). For more information how to do this, refer to the integer class documents.
Using toString() method
You need a decompiler to convert class files to java source files. JAD is a Java Decompiler that can do it for you.
There are several different methods to convert an integer variable to a string variable in Java. For example, one can use the following code to convert an integer variable to a string variable: Integer.toString(number)
To convert byte to String in java use the String(bytes, UTF-8); //example for one encoding type. You must know the special encoding that contains a variety of characters.
You can use the toUpperCase() method on a String to convert any String to all uppercase.
