Please help! converting c++ into java

Question

Thanks to the people who helped me with my last bit of text - greatly appreciated, i need a bit more help though, with calculating a basic similarity matrix and clustering. Here is what i have........
void CalcBasicSimMatrix(int nEnt, int nAtt, Entity EAM[], double BSM [100][100]) //problem here*
for (int i=0; i<nEnt; i++)
for (int j=0; j<nEnt; j++)
BSM[i][j]=BasicSimBetweenEnt(i, j, nAtt, EAM); //problem here*
double BasicSimBetweenEnt(i, j, nAtt, EAM); //problem here*
double a=0, t=0;
for (int i=0; i<nAtt; i++)
if(AT[n].Attribute==1 && AT[m].Attribute[i]==1)//problem here*
a++;
else
t++;
return a/(a+t); // is this same in java?
struct Cluster
int ent[100];
int n;
cluster Clusters[100]; //?
void initialiseClusters() //?
nClusters=0;
for(int k=0; k<nEntities; k++)
Clusters[k].n=1; //?
Clusters[k].ent[0]=k; //?
nClusters++;
void PerformClustering() //?
int method;
double SimThreshold;
max=100;
InitialiseClusters(); //?
cout<<"Enter clustering method(1=Ave Link, 2=Min Link, 3=Max Linkage):";
cin>>method;
cout<<"Enter similarity threshold(enter '0' if none required):";
cin>>SimThreshold;
while(nClusters>0 && max>0 && max>SimThreshold)
MostSimilarClusters(method);
if(nClusters>1)
MergeClusters(x,y);
The code for merging clusters also makes no sense...............
Any help is greatfully received.Thanks.

Now, I am assuming you are trying to learn Java, but have also been a C++ user. Here are some questions I need to ask:
Is there a C++ course in Ojbect-Oriented Programming offered to where you are?
What is this code suppose to do?
What parameters does it accept?
What are the return values?
Is this is a recursion part of code for something larger?
