In Groovy, "if" statements are used to execute a block of code based on a specific condition. The "if" statement can be used in conjunction with assignment to assign a specific value or object to a variable based on the condition.
Here's an example:
def score = 85
def grade
if (score >= 90) {
grade = 'A'
} else if (score >= 80) {
grade = 'B'
} else if (score >= 70) {
grade = 'C'
} else {
grade = 'D'
}
println "Your grade is $grade"
In the example above, we have a variable named score that contains the value 85. We also have a variable named grade that we want to assign based on the value of score.
We use the "if" statement to check if score is greater than or equal to 90. If it is, we assign the value "A" to grade.
If score is not greater than or equal to 90, we move on to the next "if" statement and check if score is greater than or equal to 80. If it is, we assign the value "B" to grade.
We continue this pattern until we reach the final "else" statement. If none of the previous conditions were met, we assign the value "D" to grade.
Finally, we print out the value of grade, which in this case is "B".
