Java – a method that does not return a value when “return” is encountered in “if”

My problem is that this method "islargest" encounters "return true;" Time does not end Even if the condition in "else if" is true, it seems to just skip it and always return "false" I even printed a word "test" to prove this When I use this method, it displays "test" and returns false

I tried to put this "return false" in else or other content, but then said "this method must return Boolean type" and suggested that I add a return statement What should I do?

public boolean isLargest(Node tmp,Node parent){
    if(tmp.value > parent.value){
        parent = parent.right;
        tmp.isLargest(tmp,parent);
    }
    else if(parent.value == tmp.value){
        System.out.println("test");
        return true;
    }       
    return false;

Solution

When you have a recursive call, you need to return the value of the recursive call

public boolean isLargest(Node tmp,Node parent){
if(tmp.value > parent.value){
    parent = parent.right;
    return tmp.isLargest(tmp,parent);
}
else if(parent.value == tmp.value){
    System.out.println("test");
    return true;
}       
return false;
