# Basics Java

## Operators In Java
1. Arithmetic Operator
example: -,+,/,*,%-----------/ gives quotient, % gives remainder
2. Relation Operator----output is always boolean ie true or false
<,>,<=,>=,==,!=
3. logical Operator
or-- ||, and -- &&, not -- ! 

## Conditional Statements
1. if-else
syntax:
 if(condition_true){
            }else{
                  //when condition is false   }
 
2. if-elseif ladder

syntax: if(condition_true){
       }else if(condition_in_if fails_only_then){
}else{
//when both if and elsif fail

}

3. switch case

switch(number){
    case 1: 
default:
}

if no break written all from case matched to default will be executed

## Loops

1.while
2.do-while
3.for


a. while(condition_true){//we dont know the number of iteration} <br/>
b. for(int i=0;condition;I++){we know the number of iteration} <br/>
c. do-while---
first run is mandatory

do{
}while(condition)//go back to do when true else leave the loop
