Casting

• Casting in Java can be manually done with the proper syntax.
• To do this you must use a cast, which is an explicit type conversion.

• The following syntax is used to perform casting.

(target type) variable

• The “target type” is the data type that we want to change to.
• Target data type must be kept inside brackets, and next we need to mention the variable (Or the value) that we need to get converted.
• The following example shows casting of double to integer.

num = (int) dbl;
    

• When casting floating point values to integers, the value will be truncated. (The decimal pace will be removed without rounding.)

• The following example shows casting of integer to float.

flt = (float) num;
    

• But integers cannot be converted to strings in the above method.
• Next let’s explore the process of converting integers to strings.
