//If else Statement:-

  • //the java if-else statement also tests the condition.
  • //the condition after evaluation of if statement will be either true or false.
  • //If this condition is true then the block of the statement connected to the if statement is executed.
  • //If this condition is false then the block of the statement connected to the else statement is executed.
  • synatx of If else statement.

if (condition)

{

             // block of code to be executed if the condition is true

}

else

{

             // block of code to be executed if the condition is false
