                                                           CONDITIONAL STATEMENTS A conditional statement  consists of a condition and a task . When the condition is true, the application performs the task. The condition portion of a conditional statement is also called an expression. There are four types of conditional statements in java :  If Condition. If else condition. If else If condition. Nested If condition. If condition :  The Java if statement tests the condition. It executes the  if block  if condition is true. if (condition){   //code to be executed    }   If else Condition :  The  Java   if statement  is used to test the condition. It checks  boolean  condition:  true  or  false . There are various types of if statement in Java. if (condition){   //code if condition is true    } else {   //code if condition is false    }    If Else If  Conditions:  The if-else-if ladder statement executes one condition from multiple statements. if (condition1){   //code to be executed if c
