Consider the chart while coding: Java else-if Statements - else if statements in Java is like another if condition, it’s used in the program when if statement having multiple decisions. Statements inside the body of else block are executed if the test expression is evaluated to false. In this case, the action is to simply print an error message stating that the bicycle has already stopped. to test whether x is greater than y If the result of the if statement evaluates to false and we want to action on the result, then we use the else statement. It matches each condition if it is true. However, if the test expression is evaluated to false, it does nothing. The Java if else statement executes a block of code, if a specified condition holds true.If the condition is false, another block of code can be executed using the else statement.. In the computer programming, we use one of the methods to handle this is by using the If and if else statements, also known as decision-making statements – to take the decisions based on different situations.

If the condition is true, print some text: In the example above we use two variables, x and y, Use else to specify a block of code to be executed, if the same condition is false. Java has the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true; Use else to specify a block of code to be executed, if the same condition is false; Use else if to specify a new condition to test, if the first condition is false Given below is a java program to find grade of a student using if else ladder according to the percentage of marks obtained..
