Which of the following hashCodes will result in the most collisions overtime?

public int hashCode$1()\{$

return $17$;

$\}$

public int hashCode$2()\{$

return this.weight;

$\}$

public int hashCode$3()\{$

return $($int$)$this$.$name.length$()$;

$\}$

public int hashCode$4()\{$

int sumOfASCII $=0$;

for $($int i $=0$; i $<$ this.name.length$()$; i$++)\{$

int asciiValue $=$ this.name.charAt$($i$)$;

sumOfASCII $+=$ asciiValue;

$\}$

return sumOfASCII;

$\}$
