System.out.println

[sunjavaboy]

Hello,

The java application I work on has thousands of System.out.println statements. Now I have to make all these S.o.p's execute only if a condition is true and restrict executing them if the condition is false.

I cannot put the check at all the places where S.o.p statement is written in the code. Can somebody suggest a way out where I can have one common method which I can replace it with all the S.o.p's in the application?

Any help would be appreciated.

System.setOut(PrintStream out)

or AOP

hi sunjavaboy

You Can use Initialization Blocks

print one if statement

{
if (true)
}

like that

If you still need help, perhaps it would be easier to see your posted code, or if you like your privacy, an example.

I would use for statements, like in the below code

Code:

/* place this code wherever is preferable, I apologize for any mistakes in my code */

// the total number of println statements, i used the name objects for MyPrintObject
int objects = 20;
// all the lines you don't want to print, I chose random numbers
int[] exceptions = {2, 5, 7, 15, 17}
// other variables
MyPrintObject[] p = new MyPrintObject[objects];
boolean makeTrue = true;

for (int i = 0; i <= objects; i++) {
makeTrue = true;
for (int x = 0; x <= totalExceptions; x++) {
if (i == exception[x]) // if this object is equal to one of the exceptions, make it false
makeTrue = false;
}
if (makeTrue)
p[i] = new MyPrintObject(true);
else
p[i] = new MyPrintObject(false);
}

// print objects
for (i = 0; i <= objects; i++) {
if (p[i].print()) // for information on the print() method, see below
System.out.println(i);
}

Here is an example of MyPrintObject

Code:

/* My very simple MyPrintObject class */

public class MyPrintObject {

private boolean print;

public MyPrintObject() {
print = true;
}

public MyPrintObject(boolean b) {
print = b;
}

public boolean print() {
return print;
}

}
