Read input using Scanner in Java

nextInt():

Function: Receives Integer input and stores in respective integer variable.

Syntax:

int <variable name> = <object name>.nextInt();

Example:

Scanner dprs=new Scanner(System.in);\n                  int x=dprs.nextInt();

nextFloat():

Function: Receives Float input and stores in respective float variable.

Syntax:

float <variable name> = <object name>.nextFloat();

Example:

Scanner ddlj=new Scanner(System.in);\n                 float f=ddlj.nextFloat();

nextLong():

Function: Receives Long input and stores in respective long variable.

Syntax:

long<variable name> = <object name>.nextLong ();

Example:

Scanner ddlj=new Scanner(System.in);\n                 long l=ddlj.nextLong();

nextDouble():

Function: Receives Double input and stores in respective double variable.

Syntax:

double <variable name> = <object name>.nextDouble();

Example:

Scanner soty=new Scanner(System.in);\n                 double d=soty.nextDouble();

nextLine():

Function: Receives String input and stores in the respective String variable.

Syntax:

String <variable name> = <object name>.nextLine();

Example:

Scanner soty=new Scanner(System.in);\n                 String s=soty.nextLine();

Sample Program using Scanner Class:

import java.util.*;\nclass ScannerDemo\n{\npublic static void main()\n{\nScanner inp=new Scanner(System.in);\nSystem.out.println(\"\\n Enter a Sentence: \");\nString x=inp.nextLine();\nSystem.out.println(\"Entered Text is: \"+x);\n}\n}

Output:
