Syntax error Convert Byte to numeric primitive data types in Java

Convert Byte to numeric primitive data types in Java

To convert Byte to numeric primitive data types, use the following methods −

byteValue()
shortValue()
intValue()
longValue()
floatValue()

Firstly, let us declare a Byte.

Byte byteVal = new Byte("35");

Now, let us see how to convert it to long type, for a simple example.

long longVal = byteVal.longValue();
System.out.println(longVal);

In the same way, you can convert it to other primitive data types as shown in the complete example below −

Example

 Live Demo

public class Demo {
   public static void main(String args[]) {
      // byte
      Byte byteVal = new Byte("35");
      byte b = byteVal.byteValue();
      System.out.println(b);
      short shortVal = byteVal.shortValue();
      System.out.println(shortVal);
      int intVal = byteVal.intValue();
      System.out.println(intVal);
      long longVal = byteVal.longValue();
      System.out.println(longVal);
      float floatVal = byteVal.floatValue();
      System.out.println(floatVal);
      double doubleVal = byteVal.doubleValue();
      System.out.println(doubleVal);
   }
}

Output

35
35
35
35
35.0
