First of all, there is no difficulty in this, which is to analyze the difference between break and return. From the final printing results, we can see:
1. Break just jumps out of the loop and continues to execute code inside and outside the function.
2. Return is a direct function that returns, and the code in the loop and the following function will not be executed.
Code:
package ;
/**
* 8. Write a program first and print the values from 1 to 100. Then modify the program and use the break keyword to exit when it prints to 98. Then try to use return to achieve the same purpose.

public class Test8 {
public static void main(String[] args)
{
nomDisplay();
breakDisplay();
returnDisplay();
}
public static void nomDisplay()
{
for(int i=1; i<=100; i++)
{
(i);
}
(" nom end!\n");
}
public static void breakDisplay()
{
for(int i=1; i<=100; i++)
{
if (98 == i)
{
break;
}
(i);
}
(" break end!\n");
}
public static void returnDisplay()
{
for(int i=1; i<=100; i++)
{
if (98 == i)
{
return;
}
(i);
}
(" return end!\n");
}
}
Print result:
