Wrapper Class in Java

  • Java offers for every primitive datatyes in wrapper classesin java.lang. package.
  • To define the primitives we need to use the java predefined keywords was mandatory.

For Example:

The following keywords are avaialable in javaby using this keywords only you can define the primitives in java.

byte b=45;

short s=78;

int i=89;

long l=787878887L;

float f=78.78F;

double d=78787.90D;

char ch=’M’;

String emp_Name=”Welcome”;

boolean flag=false;

Imp Note:

For every wrapper class can return primitives only.

For Example:

1.public static final byte MAX_VALUE(it will return the primitive type byte value)

2.public static final short MAX_VALUE(it will return the primitive type short value)

3.public static final int MAX_VALUE(it will return the primitive type int value)
