java - 如何使用某些值更改 for 循环

Question

我是java新手。我需要帮助解决一个基本问题。当满足特定条件时如何更改 for 循环限制？

例如:

x = 0;
y = 100,
z = 20;

for (w=x ; w<=y; w+=z)
{
    System.out.println("this is wat i needed");

    if (w==60)  
        // from here onwards i want to change z value to 4
} 

Answer 1

for(int w=x;w<=y;z=(w==60)?4:z,w+=z){
             System.out.println("this is wat i needed");
}
