Convert Java String to Long

public class StringToLongExample

{

 public static void main(String[] args)

{

Long lObj1 = new Long("100");

System.out.println(lObj1);

String str = "100";

Long lObj2 = Long.valueOf(str);

System.out.println(lObj2);

   }

}

Convert Long object to String object

public class LongToStringExample

{

public static void main(String[] args)

{

Long lObj = new Long(10);

String str = lObj.toString();

System.out.println("Long converted to String as " + str);

   }

}

Convert Long to numeric primitive data types

public class LongToNumericPrimitiveTypesExample

{

public static void main(String[] args)

{

Long lObj = new Long("10");

byte b = lObj.byteValue();

System.out.println(b);

short s = lObj.shortValue();

System.out.println(s);

int i = lObj.intValue();

System.out.println(i);

float f = lObj.floatValue();

System.out.println(f);

double d = lObj.doubleValue();

System.out.println(d);

    }

}

Convert String to long

public class StringToPrimitiveLongExample

{

public static void main(String[] args)

{

String str = new String("10");

long l = Long.parseLong(str);

System.out.println(l);

   }

}

Convert long primitive to Long object

public class longToLongExample

{

public static void main(String[] args)

{

long i = 10;

Long lObj = new Long(i);

System.out.println(lObj);

 }

}

Java Long

public class LongExample

 {

public static void main(String[] args)

{

long l = 10;

Long longObj1 = new Long(l);

Long longObj2 = new Long("5");

System.out.println(longObj1);

System.out.println(longObj2);

   }

}

Find absolute value of float, int, double and long using Math

public class FindAbsoluteValueExample

{

public static void main(String[] args)

{

int i = 8;

int j = -5;

System.out.println("Absolute value of " + i + " is :" + Math.abs(i));

System.out.println("Absolute value of " + j + " is :" + Math.abs(j));

float f1 = 10.40f;

float f2 = -50.28f;

System.out.println("Absolute value of " + f1 + " is :" + Math.abs(f1));

System.out.println("Absolute value of " + f2 + " is :" + Math.abs(f2));

double d1 = 43.324;

double d2 = -349.324;

System.out.println("Absolute value of " + d1 + " is :" + Math.abs(d1));

System.out.println("Absolute value of " + d2 + " is :" + Math.abs(d2));

long l1 = 34;

long l2 = -439;

System.out.println("Absolute value of " + l1 + " is :" + Math.abs(l1));

System.out.println("Absolute value of " + l2 + " is :" + Math.abs(l2));

  }
