I have a program I was working on and suddenly started getting unreachable code errors at my return in my columns() method. I tried any line and it won’t say anything but unreachable code. The line “return obj” is the line that can’t be reached. My code is below:
public class Display {
public static void main(String[] args){
int x,y;
for(int a = 1; a < 5; a++){
System.out.print(a + "t");
}
System.out.println();
for(int i = 0; i < 10; i++){
y = i;
x = 1;
for(int z = 0; z < 4; z++) {
System.out.print(x*y + "t");
x++;
}
System.out.println();
}
}
public static Object[] columns() {
Object[] obj;
obj = new Object[11];
obj[0] = "x = 1, 2, 3, 4";
for(int o = 0; 0 < 10;o++){
obj[o+1] = "x * " + o;
}
return obj;
}
}
Answer
Your problem is here:
for(int o = 0; o < 10;o++){
obj[o+1] = "x * " + o;
}
return obj;
You are using 0<10 this loop never ends.
