How to modify if statement by using '&&' or '||' with ASM

I want to edite the if statement in this example class:

public class foo {
    public void m0(Object o){
        if(o != null){ // I want to change this if statment
            o.build()
        }
    }
}

to somthing like this:

Example 1 with '||':

public class foo {
    public void m0(Object o){
        if(o != null || o < 0){ // I want to look like this
            o.build()
        }
    }
}

Example 2 with '&&':

public class foo {
    public void m0(Object o){
        if(o != null && o < 0){ // // I want to look like this
            o.build()
        }
    }
}

thanks in advance.
