Find a if statement which if-block is empty, without else-block

if(){<<empty>>}else{<<null>>}

Find all public methods

public <<>>(){}

Find all classes without any method

class <<>> { \<<>>(){}}

Swap if-block and else-block

if(){
}else{
}

[0.0]=>[0.1]$
[0.1]=>[0.0]$

Insert "print(a);" before if-block's first statement, and insert "print(b);" before else-block's first statement. This is a simple demo of code instrumentation.

if() {
}else{
}

[0.0]=>"""print(a);""" ## [0.0]$
[0.1]=>"""print(b);""" ## [0.1]$

Use for-statement equivalent substitution while-statement.

while (i < 5) {
}

[0] => """for(int i=1; i<5; i++){""" ## [0.0]$ ## """}"""$

Use while-statement equivalent substitution for-statement.

for (int i=0; i<5; i++) {
}

[0] => """while (i<5) {""" ## [0.0] ## """}""" $
