i have problem with this example of code, im on beginig of my way with processing...

the problem is about the condition i make


float lineX = 0;
float lineY = 0;
float lineH = 100;
float lineW = 50;
float lineStroke = 255;
float backgroundColor = 255;
float change = 0.5;
int w = int(random(1,4));
void setup (){
  size (200,200);
  smooth();
 
}

void draw(){
  background(backgroundColor) ;
  stroke(lineStroke) ;
  line(lineX,lineY,w,lineH);
  line(lineX,lineY,lineW,lineH*2);
  line(lineX,lineY+w,lineW,lineH*4);
  line(lineX,lineY,lineW,lineH*6);
lineX= lineX +1;
lineY= lineY +1;
lineW= lineW - change;
lineH= lineH + change;
lineStroke = w + 1 ;

if ( lineX >= 200) {
lineX < 200; 
    }
}


so i wish that line is swimming till it is x=200 and then coming back to 0 position,

possible is im wrong and dont undrestend the way conditionals working.....but wish to understand


thanks for patience
