GoogleRightCurly
Since Checkstyle 14.2.0
Description
Checks the placement of right curly braces (
'}') for code blocks, following the Google Java Style Guide .
For nonempty blocks the right curly brace must begin its own line, unless it is followed by else, catch, finally, or a comma, in which case no line break follows it.
For empty blocks, either K&R style or the concise {} form is allowed, except within a multi-block statement (if/else, try/catch/finally).
Examples
To configure the check:
<module name="Checker">
<module name="TreeWalker">
<module name="GoogleRightCurly"/>
</module>
</module>
Example:
public class Example1 {
static {
a = 0;
} static int a = 1;
// violation above 'should be alone on a line'
void method() {
if (a == 0) {
bar(1, 2, 3);
// violation below 'should be on the same line'
}
else {
bar(1, 2, 3);
}
try {
bar(-1, -2);
// violation below 'should be on the same line'
}
catch(Exception e) {
bar(0);
}
do {
bar(a);
a--;
// violation below 'should be on the same line'
}
while (a > 0);
}
void method2() {
switch (a) {
case 1: int y = 1; break;
case 2: {bar(-1);} // violation 'should be alone on a line'
case 3: {break;} // violation 'should be alone on a line'
default: {
bar(-2);
}
}
// violation below 'should have line break before'
if (a == 0) {bar(a);} else {
bar(a--);
}
}
void bar(int... n) {int[] k = n;}
// violation above 'should be alone on a line'
void foo() { }
// violation above 'Empty block should be concise {}'
void foo1() {} static class bar1 {}
// violation above 'should have line break after'
}
