Program:

            /* ............... START ............... */
                
public class JavaStringToLong {

	public static void main(String[] args) {
		String str = "38399383";
		// Conversion using parseInt method
		long num = Long.parseLong(str);

		// Conversion using valueOf method
		long num2 = Long.valueOf(str);

		// Conversion: Long(String s) constructor
		long num3 = new Long(str);

		// Displaying variables values
		System.out.println(num);
		System.out.println(num2);
		System.out.println(num3);
	}
}

                /* ............... END ............... */
        

Output

38399383
38399383
38399383

Notes:

  • The Long.parseLong() static method parses the string argument as a signed decimal long and returns a long value.
  • Syntax : public static long parseLong(String s) throws NumberFormatException.
  • The Long.valueOf() static method will return an Long object holding the value of the specified String.
  • Syntax : public static Long valueOf(String s) throws NumberFormatException.
