Java String Methods

  String Methods in java String.toUpperCase()   returns the String into UpperCase String.toLowercase()   returns the String into LowerCase String.charAt(indexValue)   returns the character at given index number String.replace(oldString/char,newString/char)   returns the String which is replaced with new character/String by old String/character  String.replaceFirst(oldString,newString)   return the String   which is replace of first occurance of old character/String into new character/String String.contains(checkString/character)   returns boolean value if the contain the given char/String String.concat(newString)   returns the concatenation of new String at the end of oldString, we can also use + to concat the Strings String.equals(checkString)    returns the boolean value by checking the values of 2 strings are exactly matched (case sensitive) String.equalsIgnoreCase(checkString)   returns the boolean value by che...

Looping Statements

 Looping Statements or Iterative Statements These are used to run the set of statements repeatedly. Here the statements run repeatedly until the given condition is false. We need to write a proper condition so that the loop runs finite number of times. Types of loops: while do-while for foreach 1)while loop: Here the loop executes until the given condition is false. The Initialization / declaration can be done at anywhere before the loop. Syntax: while(condition){ //statements which are needed to be execute Increment/Decrement; } 2)do-while loop: Here the statements are executes atleast one time , even the given condition is false. It is exit control loop whereas for,while are entry control loops. Syntax: do{ //statements which are needed to be execute }while(conditon); 3)for loop: Here the number of Iterations can be known. Here the initialization , Declaration , Condition , Increment / Decrement are present a single place. We can place multiple Declarations , Increments / Decreme...

Constructors in java

 Java Constructors Constructor is nothing but a method with a class name It doesn't return any values  We don't write any return type of the constructor It is used to initialise the values when the object is created In java there is constructor called default constructor it is automatically initialize when there is no constructor is assigned We can also give parameters in the constructor so at the time of initialize we can assign some value into the class. It is known as parametric construction If we create a any constructor in a class then the default constructor will not work so we need to write the default constructor also if we want to use them Ex: 1) Default constructor class Hello{ public int a=10; public int b=20; } class Hel{ public static void main (String []args){ Hello h=new Hello();// using default constructor  System.out.print(h.a+h.b);//1020 } 2) Constructor with no parameters   class Hello{ public Hello(){ System.out.print("Hello"); } } class Hel{ publ...
