In this section we are going to learn about the type conversion in Java. The term Type Conversion is Java is used for the coding process where are converting one data type into another data type. For example in the web application use can type product quantity in a text field and then data is sent to server in the String format. After retrieving the data into a String variable we can only use this in number format after the conversion of String into number.

The data conversion is necessary process in programming because one data format is different another format. For example number 10 is String can't be compared with number 10 in a Integer variable. So, in this section we are going to give you many Java Conversion examples with explanation.
