Type Casting in java

By -

Implicit conversion :
  1. The compiler is responsible for Implicit type cast conversion
  2. Whenever we need to cast a smaller data type value to a bigger data type variable then implicit conversion is used.
  3. Implicit typecast is also know as widening or upcasting.
  4. Implicit type casting no loss of information
Example  1:
int a = 'a';
System.out.prinitln(a);  // 97

In the above Example compiler converts char to int automatically by implicit typecasting.

Example 2:
double d = 10;
System.out.println(d);  // 10.0

In the above Example compiler converts int values to double automatically by implicit typecasting.

Below are possible implicit typecasting :

Explicit conversion :
  1. The programmer is responsible for Explicit type cast conversion
  2. Whenever we need to cast a Bigger data type value to a smaller data type variable then Explicit conversion is used.
  3. Explicit typecast is also know as narrowing or downcasting.
  4. in the Explicit type casting loss of information
Example  1:
Char a = (char)10;
System.out.prinitln(a);  


Below are possible Explicit typecasting :

Primitive Data Types in java

Primitive Data Types   Expect boolean and char remaining data types are consider assigned data types because we can represent both positive and negative numbers. byte : size : 1 byte  ( 8 bit) max value : 127 min value: 128 Range: -128 to 127 a byte is the best choice,  if we want to handle data in terms of streams either from file or form the network. syntax : byte b = 10; Default value : 0 short: size: 2 bytes (16 bit) Range: - 2 power 15 to 2 power 15 -1 the short data type is best suitable for 16-bit processors like 8085 but these processors are completed outdated and hence corresponding data type is also outdated datatype. syntax : short b = 10; Default value : 0 int : size: 4 bytes (32 bit) Range: -2 power 31 to 2 power 31 -1 syntax :  int b = 10; Default value : 0 long : size: 8 bytes (64 bit) Range : - 2 power 63 to 2 power 63 -1  syntax : long b = 1051541; Default value : 0 All the above data types (byte, short, int, long ) use to represent integral val...

let - Keyword in JavaScript (Block scope)

By -

Before ES2015  javascript variable has only two scopes i.e.  Global Scope   and   Function Scope . but in ES2015 they introduced the let keyword. this keyword provides Block scope variables. Block scope means  Variables declared inside a block  {}  cannot be accessed from outside the block. For Example : function getPersonDetails(){       var name ="Nilesh";       let newName = "Nil" } console.log("Print variable with var "+ name);    // you can access name variable outside function console.log("print variable value with let"+newName);  // you can not access newName Variable outside. In the above example getPersonDetails is a function that contains two variables "name " and "newName" with the keyword var and let. hear you can access the name variable which is declared with var keyword outside of the function. but you can not access the newName variables which is declared with the let keyword outside of the f...

Coding Problem 4: Smallest window containing 0, 1 and 2 [GFG - Problem Solving]

By -
  Given a string   S   consisting of the characters   0 ,   1   and   2 . Your task is to find the length of the   smallest substring  of string   S   that contains all the three characters   0, 1  and   2 . If no such substring exists, then return   -1 . Example 1: Input: S = 10212 Output: 3 Explanation: The substring 102 is the smallest substring that contains the characters 0, 1 and 2. Example 2: Input: S = 12121 Output: -1 Explanation: As the character 0 is not present in the string S, therefor no substring containing all the three characters 0, 1 and 2 exists. Hence, the answer is -1 in this case. Your Task: Complete the function  smallestSubstring()  which takes the string  S  as input, and returns the length of the  smallest substring  of string S that contains all the three characters  0, 1  and  2. Expected Time Complexity:  O( length( S ) ) Expecte...
