Bonjour,
prg suivant me donne erreur
Syntax error on token ";", . expected
i cannot be resolved or is not a field
at Fusionner.buildRandomSortedIntArray(Fusionner.java:32)
at Fusionner.main(Fusionner.java:13)
pourtant j'ai bien mis point virgule
import java.util.Arrays;
import java.util.Random;
public class Fusionner
{

private static final int NB_OF_TEST=10;
public static void main(String[]args)

for(int test=0;test<NB_OF_TEST;test++,maxLength*=2)
{
int[]increasing=buildRandomSortedIntArray(true,random.nextInt(maxLength));
int[]decreasing=buildRandomSortedIntArray(false,random.nextInt(maxLength));
System.out.println("_____________________________________________________");
System.out.println("Croissant:"+Arrays.toString(increasing));
System.out.println("Décroissant:"+Arrays.toString(decreasing));
int[]merged=new int[increasing.length+decreasing.length];
merge(increasing,decreasing,merged);

if(leftIndex<increasing.length)
System.arraycopy(increasing, leftIndex, merged, mergedIndex, increasing.length-leftIndex);
else

}
}
la ligne 13 est :
int[]decreasing=buildRandomSortedIntArray(false,random.nextInt(maxLength));
la ligne 32 est :
for(int i=0;max=array.length/2;i<max;i++)
{
merci d'avance
