Java I have a String variable "a>b && z>c && x==y" and I want to convert into a normal if conditional expression

int a=0;int z=0;int c=0;int x=0;int y=0; any more

String myarray[0] = "a>b && z>c && x==y";
String myarray[1] = "a<b && z<c && x==y";
String myarray[2] = "a>b && z>c && x<=y";
String myarray[n]

for(i=0;i<myarray.size();i++){
        if(myarray[i]){
        here code..
        }
}

Any help will be appreciated. Thank you.Thank you.Thank you.
