I have part of the code:
public void CollectorOrPocrushka(double output) {
if (output <= 0.4999999999999999999999)
System.out.println("покришка");
if (output > 0.5 && output <= 1.0)
System.out.println("колектор");
}
Can I write float number 0.4999999999999999999999 shorter?
Something like that:
0.49F
0.49e^10


If your question is about to simplify the first if condition and your goal is to check if the output is less than or equal 0.4999999999999999999999, you can easily write
if(output < 0.5)
System.out.println("покришка");

I tried to remove C++ but that didn't work.

I am trying to make a program where I can't find a solution for this:
I want to check if position_x is 0 or 20 or 40 or 60 or 80 or 100 or 120... until 1280 (always plus 20).
I hope you can help me further,
Thanks!

You can try using the modulus here, e.g.
if (position_x % 20 == 0 && position_x >=0 && position_x <= 1280) {
System.out.println("position_x is a multiple of 20 and within range.");
}
else {
System.out.println("position_x is out of range or not a multiple of 20.");
}

I am trying to print this integer 12345679 like 1,234,68. I was trying to do like this.
System.out.println(count+" "+"$"+fm.format(NumberFormat.getNumberInstance(Locale.US).format(avg)));
How can I do this in java??

NumberFormat currencyInstance = NumberFormat.getCurrencyInstance(Locale.US);
currencyInstance.setMaximumFractionDigits(0);
System.out.println(currencyInstance.format(12345679));
Output: $12,345,679

while (in > h-1 && n[in-h] >= wrapperTemp)
I am writing a program but it deals with objects, so using the >,>=, symbols aren't going to help me in this case.
in, h, and wrapperTemp are all variables.
- this is written in the java language

I think you just want this
while (in.compareTo(h-1) > 0 && n[in-h].compareTo(wrapperTemp) >= 0)

Try,
while (in > h-1 && (n[in-h].compareTo(wrapperTemp) >=0))

Hi in the below code mandatoryCount = 0 and it should be increased when an image is selected but its found to be always 1 and i cant exit the loop can any one help me. Here if mandatoryCount = 0 or mandatoryCount>=imageTypeMandatory.length. It must come out of loop. But this code is working if i comment the mandatory count ==0. I cannot find the exact error.
if (dataOne.getCount() >= 1) {
mandatoryCount=0;
dataOne.moveToFirst();
while(!dataOne.isAfterLast()){
for(int iCopy=0;iCopy<imageTypeMandatory.length;iCopy++){ if(imageTypeMandatory[iCopy].trim().equalsIgnoreCase(dataOne.getString(0).trim())){
mandatoryCount++; imageTypeMandatoryCopy[iCopy]="";
}}
dataOne.moveToNext();
}

The logic is testing the moveFirst/moveNext.
if (dataOne.moveToFirst()) {
do {
for(int iCopy=0;iCopy<imageTypeMandatory.length;iCopy++){
if(imageTypeMandatory[iCopy].trim().equalsIgnoreCase(dataOne.getString(0).trim())){
mandatoryCount++;
imageTypeMandatoryCopy[iCopy]="";
}
}
} while(dataOne.moveToNext());
}
