string type casting java code example

Example 1: int to string java

int x = 3;

Integer.toString(int)

Example 2: java type casting

// You can typecast to convert a variable of one data type to another.
// Wide Casting converts small data types to larger ones.
// Narrow Casting converts large data types to smaller ones.
// Java can automatically Wide Cast.
// Java will throw an error when trying to automatically Narrow Cast.
// This is because data is often lost when Narrow Casting.
// Narrow Casting must be done manually.

//Wide Cast:
int SomeNumber = 5;
double WideCastedNumber = (double)SomeNumber;

//Narrow Cast:
double SomeNumber = 5.39;
int NarrowCastedNumber = (int)SomeNumber;
//Note: The data that holds the decimal places will be lost!

Example 3: java int to string

Integer.toString(n) // converts n to String

Example 4: casting in java
